Mexican Ounce 

A true ounce is 28.5 grams. A Mexican Ounce is 25 grams (not 24 grams as incorrectly defined above). The reason the measurement is shorted is because it is easier to divide and multiply by 25 rather than 28.5 when converting between imperial and metric measurements. That way when it is split from larger quantities like kilos or pounds, it divides into even smaller quantities and there is no remainder.

For example:

1lb = 16oz = 400g (true measurement of 456g)
1kg = 40oz (true measurement of 35.2g)

Johnny: I went to Hector for an ounce and when I weighed it out it was 25g.

Robbie: Damn! That's only a Mexican Ounce. Last time we buy from that dude.

Mexican Saddle Bags 

When a man lies on his back and awaits for his gay lover to enter him in the missionary position. The lover then takes the other man's balls and lifts them with his hand so that he may enter the fudge box. Once the erect meat whistle enters the log pipe, the balls then drape on both sides of the shaft, thus completing the "Mexican Saddle Bags."

Wow, I gave my boyfriend some "Mexican Saddle Bags" last night. We then watched the news and brushed our teeth before going to bed...oh yeah, I also came!
