Mexican sound-off 

When two dudes point their urethral sounds at one another, waiting for the other to make the first move. There are three possible outcomes: either both sound each other at the same time, one beats the other to sound first, or both just stand there until they lose interest.

"Did you end up doing that weird thing with that Grindr hookup?"
"Nah, we ended up in a Mexican sound-off and it got too awkward."

Mexican sound off 

When two men have a mexican sound off they put a sounding rod down their urethra and stand opposite to each other, they will then start violently jerking off and the first dude to ejaculate out the sounding rod and hit the opponent will win, this is a very intense form of battle

Old amos and old james were having a mexican sound off in the wild west.
