Smegg is a word used to describe another persons love when you yourself find this person unattractive. This may simply be because of a certain feature about them that you dislike e.g they have no eyebrows (which this source finds attractive on goth guys despite what a certain person might say). Sound confusing? Look at the example.
Eww, don't tell me that's your smegg?!
