if a dude ever notices your star trek shirt and tries to engage you in some  interrogation to prove ur not a tru fan just say “why dont you go chase an asteroid?” 

scenario a) he’ll recognize that you told him off with a line said by yeoman janice rand in season 1 episode 5 of star trek TOS, the man trap, and you’ll have “proved yourself” while also making him feel like a dumbass

scenario b) he won’t recognize the line at all and you’ll walk away with the satisfaction that he is the one who is not a ~tru fan~
