When you are out somewhere and you have to take a crap really bad but you think you can make it home. While driving home you hit a bump and explode in your pants. This is a crapcident.
I was rushing to the toilet but did not make it and had a crapcident in my shorts.
when in an instant message or text conversation, the sender unintentionally screams at the recipient by leaving the capslock on. capslock + accident = capccident
"NO, I WILL NOT...whoa, capccident...sorry...
no, i will not be able to make it to the show tonight."
situation in which blackberry ("crackberry") user runs into someone or something because he/she is focused on reading or texting and not paying attention to the world and surrounding environment.
I had a craccident at the Starbucks yesterday while tyring to respond to my client and drink my double espresso, and ended up denting my fender.
