"Smeg" was adapted for use by the crew of the popular BBC TV sitcom, Red Dwarf, and comes from the word smegma, which describes the yellowy, cheesy substance found on the end of dirty penises and grimey clits.
"Get that smeggin thing away from me!"

"Rimmer, you're an absolute smeg-head."

Derivitive in most instances from the word Smegma (See: Knob Cheese), with four meanings:

1) Spoken in the show Red Dwarf (may have been used earlier than this.) and adopted into every-day culture; Similar meaning to damn or fuck.

2) Presumably an abbreviation of Smegma again; Referring to something digusting. Often an -unidentified- disgusting substance.

3)An insult. Smegma isn't the most complementary thing to call someone, so we can assume it comes from this word.

4) A company that makes various kitchen appliances such as cookers or fridges, which serve about as much purpose as the Smegma the word tend to derive from.
1) "Causality? Well, OK, you know, one event causes another, OK, but sometimes, you just gotta say, the laws of time and space? Who gives a smeg!" -Kryten, Red Dwarf.

2) "Urgh! I just put my hand in a huge pile of smeg!"

3) "You SMEG-FACED FUCKING SMEG-FACE."

4) "Whiiiirrrrtickticktickneeaaawwwm ... boom!"

There was a young lady from Leith
Who circumcised men with her teeth
It wasn't for money
Or anything funny
She just liked the cheese underneath

This "cheese" is smegma, hence a smeghead is a cheesy dickhead
