The roundabout way you have to convince certain stoners of things. Common tactics include using their delusions against them, inductive leaps, and citing universally held stoner beliefs.
Stoner: Woooo! I am mighty!
Neighbor: Dude thinks he can fly. Don't argue, or he'll jump to prove it.
Friend: What am I supposed to say?
Neighbor: Dunno. Use stoner logic.
Friend: Hey Lawrence
! Where's your cape and mask, man?
Stoner: Oh shit

back in the house before everyone knows your secret identity!
Stoner: Shhh! I'm goin'! Quite sayin' my name!
Neighbor: Well played
