A work used to describe one who is "fucking ugly." This does not mean that the particular person is have
sexual intercourse with
a person who is ugly, but rather
that the person's appearance
is (in their opinion) ugly.
When the term fugly is used, it is obviously more extreme than the word ugly, and therefore cannot have
conjunctions to euphemize or lesser
the extent of the description. For example, one cannot say "man, that dude
is a bit fugly" because really what is being said is that the dude
is "a bit fucking ugly."
