Laughing My Freakin' Fap Off

When you laugh so hard you accidentally experience self-induced sexual stimulation of the genitals, sometimes resulting in soiled pants.

Person A: Hey did you hear about the monkey that took a photo of itself? Wikipedia is trying to claim that the monkey owns the property rights.
Person B: LMFFAPO!
Pes on B: ... Hold on need to change my pants.
