look up any word, like guncle:
(to) undercunt ′ʌndəkʌnt: to be less of a cunt than someone else
1. Allie was being a cunt to a coworker but ended up getting undercunted.

2. "I'm not saying you're a cunt but the other girls at the party were all undercunting you."

- "Okay, now you can really go fuck yourself, Brad!"

The undercunt is great. It's that meaty part of the cunt that can conduct rational thought and tell a girl just how long she can hold out for that ring.
That bitch has some undercunt, yo. I had to buy her a fuckin house to get into that shit. Damn.
