When your mouth overides your ass. Talking way way to much about nothing. Not being able to stop talking.
Dude: that guy won't shut the fuck up!
Girl: yeah nigga, he's got a bad case of flapping yap syndrome.

Yapping is talking lots and lots and lots, like reneé rapp in the bridge of her single "talk too much":
Okay, having said all that
Do you still wanna be with me?
'Cause, like, I wanna be with you
Like, like, maybe even forever
Holy shit, okay, maybe not forever
I mean, like, I'm, I'm not saying not forever
I, I actually have no idea what I'm saying
Are you mad at me?
'Cause, 'cause it's cool if you are
Right? Like, I don't care
But like, if, if you are then I'm gonna resent you
Okay? I'll forgive you but
I'm just wondering, like, okay, like, is this a sign?
Do I actually hate you?
I, I just wanna be honest, right?
Like, do you still love me?

Me: Hey bro, what does yapping mean?
Bro: Oh, I'm so glad you asked!! So yapping is basically, so basically it's like where you just talk on and on for ages in great depth without stopping. Like in reneé rapp's song, talk too much. She talks a lot in the bridge and we could call that yapping because she just goes on and on and on and on and on.

A person who attempts great wisdom by yelling and yapping nonsense. Thinking that the speed and over emoting will make others listen.
I was watching this YAPPING YODA on news today, and it was so loud and crazy that I wondered how this person was reporting anything!

When two people engage in a conversation and begin yapping to the point that a 5 minute conversation becomes a 5 hour conversation (or longer). If another party is involved, the person outside the yap happy pair may end up going unnoticed within the conversation.
Lucia: Hey sorry for not including you in the conversation yesterday, we got a little yap happy. We weren't intentionally trying to ignore you.
Mara: No worries, I know you and Darcy are chronic yappers.
