Solid Snake 

A 5 hour errection. The opposite of a Raiden: 5 months without an errection.

I had a Solid Snake during my speach to the President ... I wonder why I got the job as his 'PERSONAL' bodyguard.

sexy muffin snake

as seen in jenna marble's video on how to make pet names.

you add an adjective to something delicious and add all that onto an animal.

guy: "hey can i buy you a drink?"
girl: "well sure you sexy muffin snake!"
guy: "i think i'm in love."
