An individual that bears a striking resemblance to a hippopotamus, who has an addiction to complaining, and is plagued with the problem of just sucking at life in general. Such an individual is a cross between beast, Debbie-downer, Medusa, and an incurable migraine.
The party became exponentially more enjoyable after the suckapotamus left. If I had to listen to one more complaint, I was going to cut my ear off.
When someone lures you into a conversation, and you expect it to be quick, but said person doesn't stop talking. The typical "quick minute" conversation turns into non-stop talk-a-thon that makes the listener want to paint the office walls with their own brains. Typically some type of diversion is necessary for the listener to get away.
him/her: "hey, you got a second? I need to talk to you about something.. it'll be really quick."
him/her: <-- talks and talks and talks and talks (doesn't shut up)
me: (inserts gun into mouth) *BOOM* *SPLAT*
friend: "OMG, Godzilla is coming out of the ocean, run!!!" (conversation ends).
