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
"Okay let's do the Magnum Magnus"
