Variations include going pilot to bombardier
Terms to know before going Pilot to co-pilot:
Flight Stick- when entering into an outhouse of some sort, this is the stick that the pilot must carry to rid himself of any unsuspecting "friendly" spiders that await in the toilet
Hiroshima- an awkward and yet slightly satisfying splash-back from your atomic bomb
Ace- someone that releases their "bomb" with such precision that they have no need to wipe, for it wiped itself on the way out.
Half-Ace -not quite an ace... but still refuses to wipe.
friend :"so do I!"
guy : "lets go pilot to co-pilot. I'm earning my ace"
