Pronounced "Elmo" (like the red puppet), an Lmo is a girl that is extremely hot but has 0 ass. The assumption is that the girl at one point early in her life laughed so hard that she laughed her ass off. In addition, the word is derived from the common term "Lmao" butt the "a" for ass is removed because the girl did indeed laugh her ass off.
Tristan: Man that girl is beautiful but has no ass.
Dexter: Yeah she's an lmo.
