Now I can say this with confidence so I can get it out of my system:
"He's a bloody gooner mate! A bloody gooner!"
(In reference to my college roommate who was an actual Arsenal fan)
is a Arsenal fan (or at least a focus group has advised him to pretend to be), I'm waiting for him to describe himself as "a massive gooner" in an interview and then I can finally walk into the wilderness never to be seen again.
gunners refers to the team but the fans are gooners, and have been for decades. they embrace the term and even sing "ooh to be a gooner" at matches, which is absolutely hilarious now
