Lava Flow 

A girl rides a guy while knowingly on her period...he cums inside of her and she squeezes out a mixture of her blood and his cum all over his dick...like a mixture out of a yogurt machine...thus creating LAVA FLOW.

Here it cums!!!!!!! Lava Flowwwwww!! Oh no...It hasn't burst for years like that!!! Watch out for magma! Or Smegma! Runnnnnnnnn!

Lava Flow 

An expression that describes a morbidly obese person's rolls of fat, usually, but not limited to, the torso of their body. Typically, these rolls of fat are spilling over pants, shirts, or any other articles of clothing, resulting in a visual analogy to lava flowing over a wall, embankment, or into a body of water.

"Oh my, look at that person's lava flowing over their pants!"
Or, "Holy crap, that person is so fat, its like lava flow!"

Mini-Lava Flow 

The act of having a chub cock and beating it off. When you finally cum the penis is 2” above the wrap of your hand and semen blasts in the air and some trickles down your hand like miniature lava flows.. you then flick the semen that’s around your think band pointer finger at an object eg a woman a dog a small animal and so on

Me:Damn mike Shannon’s mad at me!
Mike:why
Me:I was performing a Mini-Lava Flow for my girlfriend Shannon and I thought the lava the pooled on the bottom of my hand would look good on her so I flicked it and hit her near the eyes with it
Mike:Damn, savage
