When a man blows his load into his girlfriend/boyfriends asshole. Then his partner gets on their hands and knees with their ass in the air, and clenches their asshole, causing a burst or "volcano" of jizz to come shooting out.
Friend: Dude, I heard you and your bae did a Mexican Volcano last night.
Dude: Yeah bro. It left a pretty big mess!
Dude: Yeah bro. It left a pretty big mess!
