look up any word, like bootylicious:
1. what is you talkin?
What are you talking about?
What do you mean?
What?!
Billybob: I'm gay
Joebob: What is you talkin?!
2. what you talkin bout willis?
Implying that someone else is crazy when they're merely pointing out your foolishness.
Willis: Don't you think you'd better put the lid on that blender full of gunk before you plug it in?

Lil' Fool: What you talkin bout willis? (as he plugs in the blender)
3. How you mean?
meaning "what is your reasoning?"

It is a slang phrase that is often used with a little intentional arrogance.

In such cases, the phrase implies that whatever was just said is ludicrous. Thus, the phrase can be quite sarcastic.

This nature of the phrase was a prominent lyric in the song "Cameras" by Drake.

Similar phrases could be:

1) Hell you talkin' bout? (What the hell are you talking about?)

2) Wtf? (What the fuck?)

3) Excuse me?

HOWEVER, the phrase can also be a playful way to genuinely ask "What do you mean?" or state "I don't get it."
Example 1

Person 1: "Can you sing?"
Person 2: "Pshh. How you mean? Hell YEAH I can!"

Example 2

Person 1: "Wow! I didn't know you were so smart!"
Person 2: "Uh, How you mean? Duh..."

Example 3 - "Cameras" By Drake

"How you mean, How you mean, Thought you knew about the Team."

Example 4

Person 1: "It's hot as hades in here!"
Person 2: "Hot as Hades? How you mean?"
Person 1: "You know! Hades! The Hell in Hercules!"
Person 1: "Ohhh!"
4. Dats What I'm Talkin' 'Bout
An expression to show that you like something.

This is the slightly more slang version of that's what i'm talking about.

Also see the acronym for this term:DWITB.
(After taking your first swig of beer after a long day at work)
Oh man, dats what I'm talkin' 'bout!

5. rap is crap
First, I would like to say I like all different types of music. One of my favorites are rap tho. The previous guys who said rap is crap are obviously narrow minded racist idiots.

*All rap doesnt sound the same* You got Nelly, Chingy, Lil Romeo, and Stagga Lee who are all jus horrible and full of garbage. On the other hand you have Wutang Clan, Ice Cube, KRS-One, Nas, Rakim, Canibus, Tupac, Biggie and others who express their background and life, and send out important messages. As in all types of music you have the garbage, in the case of rap it is the commercial music, and the good, in the case of rap it is the underground music that the hip hop heads know about and others dont know about.

Most white people that hate rap have only listened to today's commercial garbage and not the real underground shit. Some just are dickriding punks.

So "rap is crap" is a inaccurate saying that narrow minded dickriders use to refer to all rap even though they havent heard all kinds of rap.
punk rocker: "dude, rap is crap" we rock fans all hate rap

rock fan: What are you talkin about fool. Wutang is the shit, Run DMC is the shit, Nas is the shit. Steven Tyler's down with rap too, you narrow minded idoit
