To trevor implies going from being totally relaxed and snoopddoggily chilled to going motherfuckin crazy shit ass ballistic within 2.25 seconds.
To trevor got its meaning from that crazy fucked up meth taking piece of a shit Trevor in GTA V. If you ever meet someone whos trevoring around, you better catch that next train to Takemeaway Fromhere.
Oh and Trevorpeople also punch people for no reason whatsoever.

Trevorguy: Would you shut the hell up you hispanic punk ass bitch!!!
