Elephant Knee 

Larger version of Moose Knuckle. An exceedingly large version of a camel toe.

Dude, what's up with the zoo in here today?

What?

So far I've seen a camel toe, a moose knuckle and an elephant knee.

You're sick, dude.

Elephant Knees 

When you knees can't support your fatass body so they get bigger and bigger.

Jesse-Hey did you see Tate's elephant knees?

Justin- Yeah how could I miss them big mother fuckers.
