A playful slang for excessive cursing or swearing, inspired by Deadpool's notorious foul mouth. Just like the slang "threadpool" with this same meaning, the act of "deadpooling" of curse words emphasizes the chaotic and humorous nature of swearing in conversation.
After that last meeting, I unleashed an entire swear jar of deadpooling at home; I couldn't help it!
Deadpoolicorn is the Merc with the Horse's Mouth. HornyWilson from Earth 6969 ended up stranded on our planet and now helps fight evil and chaos by dressing as Deadpool. He also cosplays alot at local conventions.
That Damned Deadpoolicorn has a panel at NCComicon again!
