an accident resulting from an individual behaving like a dick
The drunk guy climbing and falling off the bar was a total diccident.
The man was killed when he diccidentally fell off his motorcycle when trying to ride it like a surf board.
Euphemism for masturbating.
Origin - somebody from our office building appears to masturbate in the 4th stall in our shared bathroom every afternoon.
"I don't feel much like going out tonight. I'm going to 4th stall it at home."
"It's been a slow day at work - I 4th stalled all afternoon."
