A Mexican quarter is when there is a hole in the bottom of a man's trouser pocket. Through this hole the man can access the head of his penis. Upon request the man can show his Mexican quarter out of his trouser pocket.
Tom, can I borrow a dollar? No, but you can have this Mexican quarter Larry. Tom, what is a Mexican quarter? Tom then proceeds to present his Mexican quarter to Larry.
