holla back 

Umm, it could not be simpler. "Holla" means "holler"... which means "to shout".
If you want to be all ghetto about it then you can use it somewhat inappropriately within a conversation to the effect of: "please reply", or "talk to me".

Colloquialism: "Hey dogg, I know dat you be cool wit' THOSE cats, why don't you holla at yo' boyz?!"
Text Message: "wut b gwanin? i b cotchin in da toilet. u goin to da club l8r? tb/holla back xxx"

holla back 

it's slang, y'know "holla." Actually it's much less complicated then everyone is making it out to be. It can be traced way back to Marvin Gaye: Inner City Blues (Make me wanna holla)...think about it.

Etiquette dictates that if i holla at you, holla back

Holla back 

Reciprocating oral sex, going down on someone after they go down on you.

If I'm going to blow him, I expect him to holla back.

holla back 

correctly spelled 'Hollaback', a word made up by Christina Aguilera that subsequnetly has no uniform definition.

I suppose it is said to gain attention, or do something once more. It might also mean 'scream backward', which makes little sense in and of itself.

Person #1: I Listen to the song Holla Back girl yesterday, I think my ears are still bleeding.
Person #2: Why can't Christina Aguilera die already?

holla back boy

A guy that sits around waiting for a chick to call for his services. Most of the time this guy is not worth dating but can be used to satisfy certain urges.

My date didn't give it up so I called Todd my holla back boy to satisfy my needs.
