To excrete an enormous amount of flatuance into the office chair you are sitting on while working. Then let permiate into the fabric and cushion of the chair. When an unexpecting co-worker walks by your cubical you let them pass by and then call them.
When they turn around and walk towards where you are sitting, you slowly get up and gently push the chair over to them and marvel at the disgust on their face.
Do da do, Ahhhhh... "Hey Harry, check this out for a second" (office chair is pushed gently towards Harry as he is walking towards you) (Harry's reply) "NO Dude! Your not right man that fuckin disgusting!" HAHAHAHA that must be your first chair bomb.

Get the Chair Bomb mug.
Works best in the office and requires impecable timing. On the day after a great, gassy meal --for instance Corned beef and cabbage and a case of beer.... with a side of spicy sausage--wait for an unsuspecting person to leave their seat. At that time, carefully, sneak into their chair and bequeath a steaming load of hot anal vapors directly into its cushion and return to your desk. When the person returns and sits back down they will detinate the "Irish Chair Bomb."
1. When my nose-hairs started to burn, I knew I was a victim of an Irish Chair Bomb.
2. Travis Irish Chair Bombed me today and I almost fucking puked.
