A sexually-transmitted condition that occurs during coitus and cures itself immediately upon separation of the pubic areas.
This condition is caused by the rough shaven pubic hair of one partner becoming entangled in the curly unshaven pubic hair of the other partner. As the name suggests, it would create a velcro-like fastening of the 2 crotch areas, requiring a substantial force to separate them.
Symptoms include: decreased ability to retract, loud ripping sounds from the genital area, and hair loss.
Johnny's bushy-haired girlfriend is walking funny today because he gave her velcrotch last night. It ripped the muff clean off her.
