It's a phrase that originated in the 1990s as a cleaner way of saying "blow me", and it's what someone says in response to something/someone who offends them, similar to "f*** you", but far less rude. Example: Person A: "Hey person B, have you gained weight? You're looking a lot heavier these days." Person B: "Bite me, Person A!"

First of all, It's not a nice thing to say (yeah, it's rude) and it means something like "kiss my -pretty- *** " "get lost" "leave me alone" ... normally used when you DON'T CARE about what the other person (or the entire world) is saying to you. :-) ( http://www.italki.com/answers/question/66834.htm )

It's the same as saying "Don't mess with me" or "F*** off!"

" Love bite", if you are not in love, "bite me" is in an opposite meanings: A slightly more polite way to say "Fxxk off you prick".

i agree with all.
