Any form of delay or douche-baggery resulting in either a check fire or end of mission. Usually employed by helicoptersflying around knowing the gun target line and blatantly disregaurding it in order to try and steal a kill from artillery. This is done because frankly helocopters just aren't sneaky enough to get their own kills, and staff officers swing from air support nuts.
Fister 1: Shot tgt#1234, check fire we have helos on the gun target line.
...an hour later.
Fister 1: Cancel check fire, end of mission this shit took way too long and helos scared them away.
Fister 2: Dude we just got fire mission cock blocked!
A term describing the unbearable burning feeling you get when you masturbate and then take a piss immediately afterwards. Don't pretend it's never happened to you.
Dude, I drank like four cups of coffee and then I saw that tall chick in a miniskirt. Long story short, I got firecock like you wouldn't believe.
