Short form for 'gay bashed'.
Sometimes used to avoid having to say 'gay bashed' since if someone hears that, it might cause a gay bash.
Me: OMG this is a sketchy place.
Foo: Yeah, I hope we don't get gashed!
Stop acting so gay, we don't want to get gashed!
used as a way to say somebody has been beaten up, taken from the word 'gash' in a cut/bruise sense.
