In Grand Theft Auto V, when you switch to or play as Trevor Philips in free roam, he says "It's Trevor Time!". 

This catchphrase is frequently accompanied by him acting erratically, such as waking up in his underwear on a beach, standing on a pile of bodies, or shouting at pedestrians.He does not say "Team Trevor Time" in the base game's free roam, as the phrase centers on his own unpredictable, self-centered, and often chaotic nature.
