The act of pushing your head deep enough into a woman's vagina so that your tongue can touch her anus. Thus, you appear to be wearing an attractive top hat. It is Mexican because the tongue to anus is absolutely disgusting and dirty.
I got a Mexican Top Hat from my girlfriend last night, and it was the sickest thing I've ever experienced.
