"Smeg" is mainly used as a kind of swear-word on the TV show Red Dwarf. When used in this context, its use is similar to that of "fuck".
Oh smeg! = Oh fuck!
What the smeg is going on? = What the fuck is going on?
Whats that smegging thing? = Whats that fucking thing?
I dont give a smeg = I dont give a fuck
1) Smeg: Exclamation of surprise not unlike fuck.
2) Smegger: Obnoxious person
3) Smeg head: As 2
2) I'll nut the smegger into oblivion
3) I'm not an insubordinate man by nature. I try and respect Rimmer and all, but it's so hard because he's such a smeg head.
this really smegging sucks
"Rimmer, you're an absolute smeg-head."
"Eww, that boy had a right load of smeg on his bell"
Salesman: i reccomend this one-Its got Smeg on it.
Sequioia: who would do that?
Salesman: i assume some guy in the German factory.
Sequioia: ah, i thought it was only us women that orgasmed on washing machines during spin cycles......
Salesman: thats not what i meant- can i interest you in a new washing machine?
