In a meeting, Up in front,
A gurgle happens in my gut.
Sensation growing, moving down
Please Oh Please, no Noise of Brown.
Pinching cheeks with all my might
Hope to God the Seals' tight.
If it happens, and my Crack gets tacky
I'm so fooked...My pants, light khaki.
Presentation, finish quick
The smell escapes, makes people sick.
No I can't take any questions
Must go deal with Indigestion.
Throwing People out of my way,
they'll be sorry if I stay.
Run for bathroom Doing fine,
Grab A stall, thank God no Line.
Explosion Happens, volume triples
Did Crapnel chunks just hit my nipple?
I made it through, and tamed this beast
Hold my Breath and Sigh Relief.
Into room They come,
as Toilet Drains,
As I proudly walk, the walk of Shame.
