Mexican Gram 

Refers to a skimped sac of black tar heroin, normally weighing out to 7/10ths of a gram instead of a whole gram. The reason dealers practice such "Jew behavior" is because heroin addicts will only bitch and moan about being jipped for less than a minute, until they can't stand feeling sick, and thus they'll take what they can get at that time. This doesn't excuse the dealers for their shitty service however, and they should be ashamed for having such poor practice. The only time a Mexican Gram would be remotely acceptable, is if the quality of the heroin is so balls-out amazing, that the users joined "team Nod-Squad" instantaneously after smoking/slamming/snorting/booty-bumping that shit.

My dealer is such a Jew for selling me a Mexican Gram time and time again.

Mexican key

A brick, paper-clip, or lock pick set. Preferrably the brick, since Mexicans can't afford lock pick sets.

We couldn't open the front door, so we used our Mexican key to get in.

Mexican Whisper

When a person or group of persons talk in a whisper tone with a normal volume loud enough to be easily overheard. Sometimes, but not often used intentionally as a threat or intimidation tactic.

I ducked into the nearest store after I heard some people Mexican Whisper that they were going to steal the gringo's wallet and let their dog rape him.

Mexican birth control 

Mexicans, by way of being Catholic, are not allowed to use birth control methods.

Instead, their birth control consists of pulling out before the point of conception.

See example.

Guy: Oh shit, we can't hook up I don't have a condom
Girl: We can just use Mexican birth control
Guy: Fuck yea, thanks Mexico

A large flock of in-flight pelicans flying in formation.

Two surfers in the water waiting for a wave, " Dude, check out the Mexican Air Force rollin' in at two o'clock.
