horny rhino 

The act of shoving your knee up another's ass from behind as a form of a sneak-attack.

"Man, that horny rhino he just gave me hurt like a mother."

rhino horn 

When your doing a girl doggie style and you jam your thumb in her ass like a rhino attacking.

I was all sweaty banging your mom like a pig and she grunted when I gave her the rhino horn.

three horn swamp rhino 

Women that are very very fat that hit on you at the bar. So disgusting that not even the light switch can justify that one.

That fat girl at the end of the bar is a real three horn swamp rhino.

Rhino’s horn 

An eye wateringly large and dimensioned dildo that defies the laws of physics in regards to the human body. Also a similar length and girth to a rhino’s actual horn.

I was on this girl’s bed and we were fooling around when she reached into her drawer and pulled out a hell of a rhino’s horn. It wouldn’t have been a fair contest so I apologised and immediately left.

rhinoceros horn

when you bang a chick so hard, your dick comes out her back. It is the most extreme of all banging.

"dude she feels so sore after last night, do you reckon he gave her rhinoceros horn?"
