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.

hand in a huge pile of smeg!"
3) "You SMEG-FACED
