Post Wall Woman
A woman between the age of 30-35 thats hit her beauty peak and is starting to decline in attractiveness. Remember the saying "Men age like wine, Women age like cheese", well its real. They tend to get fat, their boobs sag, especially after having children, and their vagina looks like a roast beef sandwich that went ten rounds with Mike Tyson.
Example:
Post wall woman: I'm so sexy
Men: Nah you've already hit the wall, you're beauty is long gone
Post wall woman: I'm so sexy
Men: Nah you've already hit the wall, you're beauty is long gone
