Usage
What does lip- mean? Lip- is a combining form used like a prefix meaning “fat.” It is used in many scientific and medical terms. Lip- comes from the Greek lípos, meaning “fat.” It is not related to lip, as in the part of the mouth; that word is actually connected to the combining form labio-. The combining form lip- is also not to be confused with a second sense of lipo- meaning “lacking” or “leaving.”Lip- is a variant of lipo-, which loses its -o- when combined with words or word elements beginning with vowels.

Etymology
Origin of lip
First recorded before 1000; Middle English lip(pe), Old English lippa; cognate with Dutch lip, German Lippe; akin to Norwegian lepe, Latin labium
Explanation
Your lips are the external, fleshy part of your mouth. You have a top lip and a bottom lip. Lips are what make kissing possible. Lips are useful when it comes to speaking, eating, and kissing. If you say that something is "on everyone's lips," you mean that it's the topic everyone seems to be talking about lately. If an angry teacher says, "Don't give me any lip!" he means "Don't be a smart mouth," or "Don't be impertinent." When you manage to keep a "stiff upper lip," you stay brave even when things get difficult.
