Bastardized spelling of the word "lovely". They (lovely, lovily) both mean the same thing.... DEFINITION:see the word "lovely". Shoot, one can argue LOVILY even means more love cuz it's got that ILY shizz.
GF: How do you spell "lovely"? (She often asks him for an answer, because she trusts him and he doesn't blow it often.)
BF: "Lovely? It's spelled: l-o-v-I-l-y. Lovily."
(He answers like he knew, but don't. He fuckin' blew it.....but they still love each other.)
GF: Wow ur dum!
