Mexican long jump 

The sexual act of performing an aimed long jump onto your partner and simultaneously inserting your dick in as the jump lands. Events include the oral Mexican long jump, back door long jump, and classic Mexican long jump.

Dude 1:"Whoa, did you see johnny miss that Mexican long jump?"
Dude 2:"Yeah man, some pretty painful shit, he got his dick cramped into the ground..."
