swamp weasel

An incompetent fool who makes brash and arrogant statements but fails to actually achieve anything. Tries to squirm into gigs by backstabbing others and succing up to the higher-ups.

"Hey, you know how Kartik said he would get first place?"
"Yeah."
"Turns out he didn't even win anything at all, and I also heard that he sucked up to the officers to get a second chance."
"LMAO this clown is the biggest swamp weasel I've ever seen."
