A G-Nap occurs when you nap with your hand on your 'piece' (cock) inorder to provide your penis with some mild touching but ensuring your load is saved for later (perhaps you are saving your load for something such as a party that starts soon or a girlfriend whom you have not seen in some time).
"Damn Jill was coming over in an hour and even though I was hardcore horny I wanted to save it for her so I just took a G-Nap."
"Shit, I betta just take a G-Nap cause that party starts in 2 hours and you know ima hook up wit some of those bitches"
Cigarette: Northern slang for a cigarette, used oft by mashed up mancunian ravers becasue of the resemblance of a hot(electric)stove to the end of a lit cigarette. Originated circa 1991 in the early halcyon days of the rave culture; we speculate during a drug fuelled hallucination by said manc.
'fuck me noel, i am bolloxed, is that a ciggy in your mouth, or the stove from me 'nans kitchen'/
General use: 'Give us a stove you cunt'
