Drag queens are performers - usually gay men, sometimes transgendered women - who dress in drag, clothing associated with the female gender, usually highly exaggerated versions thereof. Drag queens often do drag to perform, singing or lip-synching and dancing, participating in events such as gay pride parades, cabarets, discotheques, and other celebrations and venues.
We consider them part of the transgender community. The same can be same for drag kings.
