Bring out the gimp!
Some people find the name of the most popular open source and GPLed image manipulation program slightly funny or rude, others as a derogatory term, while others just see it as the acronym for GNU Image Manipulation Programme. I think a lot of English speakers fall into the first or second camp unfortunately.
Gimp is a usually derogatory term used to refer to a (male or female) sexual submissive person, typically dressed in black leather (or rubber), often in a gimp suit, and wearing a bondage hood or mask of the same material. This apparel emphasises sexuality by drawing attention to the crotch and chest, and also sexually objectifies the wearer. Sadomasochistic practice often features in the notion of the gimp, with a partnership of power exchange between gimp and dominatrix or dominant. It can also imply that a male has a smaller than usual penis.
Yeah, I use the Gimp to draw everything…
