When a guy is in such a grumpy, pissed-off state, it's like he has male PMS.
A very irratible dude. Is known to become easily pissed off, brash, rude and sarcastic.
Dude, I was at TMobile the other day, and the guy helping me was totally gillin. I asked him to show me how to change the apps on my phone and he totally bit my head off!
