The act of giving someone a "Thug Nafty In Yo Mouf" is as follows:
The man is receiving oral sex, then proceeds to urinate AND ejaculate into the female's mouth. After he is done, he looks down at the dumb whore and says "I just 'Thug Naftied in yo mouf bitch! Now go make me a damn sandwich"
"Hey Lisa, if you come over tonight, I'll give you a ThugNafty In Yo Mouf."
To stop pushing through an obstacle and instead dealing with it head on. To be strong enough to see the boulder in front of you and break it.
"I was going just keep thugging it out, but, I think I need to face this problem now, instead of just continuing to remain strong. Instead of remaining strong, maybe I need to face that obstacle, break it, and remain weak for a little bit. After that, I'm sure I'll come out stronger than before. Sometimes, you just have to thug it in."
One who usually does not have friends in the real world. Because of this, they resort to thugging it up on the internet. If you saw them in real life, you'd probably laugh. Quite popular on MMORPG's.
