A common method for manipulating files (and sometimes text) under a graphical user interface or WIMP environment. The user moves the pointer over an icon representing a file and presses a mouse button. He holds the button down while moving the pointer (dragging the file) to another place, usually a directory viewer or an icon for some application program, and then releases the button (dropping the file). The meaning of this action can often be modified by holding certain keys on the keyboard at the same time. Some systems also use this technique for objects other than files, e.g. portions of text in a word processor. The biggest problem with drag and drop is does it mean "copy" or "move"? The answer to this question is not intuitively evident, and there is no consensus for which is the right answer. The same vendor even makes it move in some cases and copy in others. Not being sure whether an operation is copy or move will cause you to check very often, perhaps every time if you need to be certain. Mistakes can be costly. People make mistakes all the time with drag and drop. {Human computer interaction} studies show a higher failure rate for such operations, but also a higher "forgiveness rate" (users think "silly me") than failures with commands (users think "stupid machine"). Overall, drag and drop took some 40 times longer to do than single-key commands. [Erik Naggum <erik@naggum.no>] (2007-06-15)

In computer graphical user interfaces, drag and drop is a pointing device gesture in which the user selects a virtual object by "grabbing" it and dragging it to a different location or onto another virtual object. In general, it can be used to invoke many kinds of actions, or create various types of associations between two abstract objects.

Drag racing is a type of motor racing in which automobiles or motorcycles compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly , with a shorter, distance becoming increasingly popular, as it has become the standard for Top Fuel dragsters and Funny Cars, where some major bracket races and other sanctioning bodies have adopted it as the standard.

No, the beige carpet wasn't striped - until Snot discovered drag racing!

The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot").

Drag Queen Story Hour (DQSH), Drag Queen Storytime, and Drag Story Time are children's events first started in 2015 by author and activist Michelle Tea in San Francisco with the goals to "inspire a love of reading, while teaching deeper lessons on diversity, self-love and an appreciation of others. The events, usually geared for children aged 3–11, are hosted by drag queens who read children’s books, and engage in other learning activities in public libraries.

A lemon drop is a sugar coated, lemon-flavored candy that is typically colored yellow and often shaped like a lemon. They can be sweet or have a more sour flavor.

A lemon drop is a vodka-based cocktail that has a lemony, sweet and sour flavor, prepared using lemon juice, triple sec and simple syrup. It has been described as a variant of, or as "a take on", the Vodka Martini, but is in actual fact a closer to a White Lady variant.

A drop test is a method of testing the in-flight characteristics of prototype or experimental aircraft and spacecraft by raising the test vehicle to a specific altitude and then releasing it. Test flights involving powered aircraft, particularly rocket-powered aircraft, may be referred to as drop launches due to the launch of the aircraft's rockets after release from its carrier aircraft.
