bluffin with his muffin~
Meaning: for a male to take out his penis, then work on it for a growing erection but not rock solid yet!
Example: My buddy had his friend over the house while all of them went Nude. Then the buddy went into the restroom and was bluffin with his muffin, when my buddy's wife came in and took full control over his cock and got it rock solid doing oral on it~
