Nasty Gal 'NG'

A girl who frequently makes questionable decisions that climax in her deciding to have sex in public toilets (especially in the NW1 area) swallow vegetarians' jizz and encourage their sexual partners to eat their own come in a show of solidarity. They are also known to grind like they are working for tips (especially in open spaces, such as public parks) and often get referred to as NG's in street talk. Fun fact-NG's often drive MG's (trophy versions) - fancy that!
