Get the Smeg It! mug.
Comes from the word "smegma", meaning the cheesy crud on the end of your dick, if you're a guy and dont wash your dick properly.

"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".
Smeghead = fuckhead
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
etc...

2) Smegger: Obnoxious person

3) Smeg head: As 2
1) Oh Smeg! What the smeggin' smeg's he smeggin' done?!

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.
