Did a Glenn 

Glenn has nothing going for him so needs to take advantage of everything he encounters in order to survive. Lacks empathy or any recognition of his actions
Uses sex (as a sub bottom) to score free lodging, food and drugs. Frequently known as a troll/ bridge troll/ cunt troll 'cos he's fat, ugly and gets what he wants for nothing.

'Doing a Glenn' means a sad, desperate act without realising that you're a sad desperate cunt

Mate 1: Dya hear what Jimmy got up to last night?
Mate 2: hell yeah, he had his heels behind his head before the queued-up slammers could lube up
Mate 3: Bitch did a Glenn... got high for a fuck

Glennenvy 

A feeling of grudging or somewhat admiring discontent aroused by the possessions, achievements, or qualities of Glenn.

Krishna: OMG there's Glenn, I think I'm in glennenvy. What remark can I make to disguise the envy I have for him and the multiple glenngasms that I'm having? Maybe I should ask glennfucious if I am worthy of being in his presence.

Glenn 

Impatient and intolerant person.

"He doesn't wait, he doesn't queue, he doesn't take detours, he doesn't take second opinions and he doesn't take no for an answer; he's a Glenn."
