Sphincter slam

When you fart so loudly both your butt cheeks close simultaneously

Most of the night you want to go to the bathroom & do a sphincter slam but you don't for fear it'll wake up the neighborhood

Sphincter scale

The measure unit of a fart based on it's intensity/ sound

Ex 1: I just ripped one of 8.5 on the sphincter scale
Ex 2: that wind was for sure a 9.1 on sphincter scale, had it been passed 10 I would've shart those pants

sphincter crunch

A workout where you clench your anus repeatedly to build stronger butthole muscles

Thomas accidentally let another fart slip out in class today. He should start doing 30 sphincter crunches every morning to build a stronger ass core.
