McFlurried 

When your girl is giving head in the McDonalds bathroom, you cum on her face and she says (in the style of Punk'd) "I've just been mcflurried!"

Grimace: Hey man, what did you guys do last night?
Ronald: We went to McDonalds for dinner and I McFlurried that bitch in the handicap stall!

Mcflurrin 

The act of purchasing mcflurries from the drive thru of a sketchy McDonalds. Must be done late at night with fellow mcflurrers. To become a mcflurrer you must be initiated.

Yo Shlyn lets get the box later tonight and go mcflurrin.
