Stands for "Cunt I'd Like To Fuck" much like the term m.i.l.f. (mom i'd like to fuck). Refers to a girl of particular sexual attractiveness. see also YCilf (young cunt i'd like to fuck), meaning the same as above, but more juicy.
"check out the cilf on the other side of the road" "ycilf!!!" (whilst walking through a school dinner hall)
