The act of when a woman has a vagina so loose, the man fits his entire head inside of it.
Stacy's mom was so loose, she graced me with a mexican face-hat
by Stacy's mom May 07, 2005
an act so vulgar and so distasteful that no one has ever been able to conceive of it.
i think i once knew of someone who knew someone who said "mexican face-hat" in his sleep, but i'm not sure.
