buttgasm

the greatest sh-t of your life. clenching you cheeks on the way to the toilet, praying you make it on time. when those sweet buns finally touch the seat an overwhelming feeling of pride and relief overcomes you and one cant help but squeel in satisfaction.
mike: dude i heard some pretty wierd noises coming from the bathroom.

chris: oh i was having a b-ttgasm

mike: you know how i know you’re gay?
it’s like an -rg-sm, but in your -ss.
i crammed this bannana in my -ss and proceeded to experience a b-ttgasm.
after holding in rectal sepage for a long while, and finally being able to sit on the toilet and let it go. the rectal sepage comes out at an alarming rate and you seem to show symptoms of having an -rg-sm. can be induced by continual diarrea.
could be pull over? i feel a b-ttgasm coming on.
when you let off such a large, relieving fart that just makes you feel so much better that you achieve a state of euphoria known as the b-ttgasm.
an hour after i ate a bunch of burritos, i farted so much that i had a b-ttgasm!
the rush of relief experienced after dropping a persistent t-rd.
“the toilet at work was broken so i held my t-rd all day. when i got home and sh-t i had the biggest b-ttgasm of my life!”
