Refers to where you sit quietly behind a big clueless dude who's eagerly chowing down on a huge plate of baked beans, "
bide your time", and then fire off a starter-pistol just as said dude is starting to "
rip one", thus igniting the unsuspecting dude's expelling methane and creating a humongous blowtorch-fireball out his ass. Extra points if (A) you loaded the gun with full-flash blanks --- both for a more spectacular effect and to better ensure that the muzzle-flash would indeed ignite the gas --- and (B) you chose a dude who usually has fairly "extended" farts instead of merely "little toots", so that any spectators can be treated to a real "light show" instead of just a brief
flare-up.
Startled guy with a smoking pants-seat: Oh, Jeez
Louize ---!!! When you fellas invited me over to your
backyard barbeque to "shoot the breeze", I never expected that you'd mean it in a LITERAL sense!!
