Basicallyyou know you're walking down the road, you see this chick from behind and she looks fine, but when you see her from the front, she's pure custbag
Similar to "douchebaggery", means something along the lines of "the act of being a massive cunt". Used when the term "cunt" would be more appropriate than the term "douchebag".
A bitch that can suck moose dick and die of disentary in the middle of the Arctic with no one to save her and then be eaten by ravenous polar bears and shat out into the icey depths to be consumed by hag fish and then reincarnated as a naked molerat so she looks like a penis with teeth that no human man will ever want again.
A woman or man whose the biggest asshole of them all. Usually they are proud of the fact that they can be difficult, however when called out on their bullshit, they never care to correct the problem.
Did you see how Joanie just called her man out like that in front of everybody? She's a big cuntbag!
