Magnum Mark 

Magnum Mark is a name I made up for my best friend in the entire world. It is something that will boost his self esteem so high that he will love me forever. "Magnum Mark" got it's name from the ice cream section at Walmart when we saw the ice cream brand called Magnum, there is a white kind and a black kind. Mark is definitely the white kind. I also know he is a "magnum" because I got drunk one night and told him he was "packin'. That's a good friend right there.

Hey girl hey, there is a Magnum Mark over there next to the big tall black guy with the big feet.

The act of plunging one's dick into the mouth of a ginger female and then shoving a magnum up their ass. Often occurs when your freezer is broken and you have extra magnums thus need to get rid of them. Can also be done with rockets however this is called red rocket Husted.

"honey, the freezers broke and the magnums are melting'

"Shit, I don't know what do you think
