Laughing my ass firmly in place- When you see some funny shit but know you're dead if you burst out laughing. Can also cause a Tallahassee giggle, where holding in a serious laugh causes unexpected and clearly audible squeak-farts.

*Sees asshole boss trip and fall on face from across the office*
*Clenches fists to contain sheer bellows of pleasure and maintain composed and professional demeanor*
