Mexican Blackjack 

Taking your used condom off your cock, proceeding to shit inside it, tying off the end and then creeping up behind your girlfriend like a burgler and smacking her in the face with it.

After banging his prudish girlfriend he pulled the condom off his cock and turned it into a Mexican Blackjack to dummy her upside the head with so she would quit asking about dinner.

Mexican Backpack 

A racial term to describe the leaf blowers that landscapers wear. Typically, the engine of this type of leaf blower is strapped to the worker's back while the hose runs down their arm to their hand where they can direct the air stream.

Whoa! Check out the Mexican Backpack on that guy! It looks like a 44cc dual-ring piston engine, and WOW a hip mounted throttle controls with cruise control. Now that guy can still work AND be lazy.
