Flava Flav chased his family around with knives

Flavor Flav was arrested in Las Vegas early yesterday morning for domestic violence, because apparently you're not allowed to chase people around the house with knives anymore. Oh, I'm sorry, I thought this was America.

According to the Vegas police report, the argument between the rapper and his 39-year-old fiancee started over accusations Flav had cheated on her -- and quickly turned violent, with Flav grabbing his fiancee and throwing her to the ground twice.

Wow. Flav is 53, drunk, and weighs 100 pounds. This chick needs to work out.

Flav's fiancee claims her earring was ripped out during the altercation ... and her 17-year-old son jumped in to defend her.

Not to defend his actions, but what did this lady think was gonna happen when she started dating Flava Flav. Did she think they were gonna go to his lake house and read a book by the fire with a golden retriever at their feet? No, when you date Flava Flav, it's cheating, chaos, and knife fights.

At that point, Flav grabbed two knives and chased her son around the house -- eventually kicking down a locked door to get to him. Flav then allegedly threatened to kill him.

Wasn't that threat pretty much implied when he chased after the kid with two knives? Yeah, Flav, we get it. You're not exactly subtle.
