Rob's mom, who resides in Winooski, is the hottest piece o' ass in Winooski. As the butt of 'rob's mom' brand jokes, one must take a suggestive or euphemistic line in a conversation and immediately append the phrase "that's what rob's mom said" because Rob's mom totally gave it up to Malkovsky.
Sexxy Nate: "Hey Rob, did you really go to the deep south for love?"

Rob: "It wasn't love, it was sex."

Sexxy Nate: "That's what rob's mom said."

Rob: "I will kill you and your entire family."
