When someone types a rant or sentance with unnescessary CAPSLOCK madness
A CAPgasm is a sentance or rant that is posted with the CAPSLOCK button activated. often used in place of exciting information to express anger or get attention.
"Dude, whats with your status? why the CAPgasm? It's not that big a deal."
"Wow, what a dick, just posting one big CAPgasm and expecting us to care"
