A Stu Stu is a male who is obsessed with showering, extremely cheep but always broke, is too busy giving advice to take any and over uses the following words: Yuck, Meow, Cute and Sweetie
A Stu Stu Meow looks very yuck today. When Meow gets out of the shower Meow will let you take me to Chili's for a Frozen Margaritas, does that sound good Sweetie? Oh, you should go put on that cute surfer girl shirt I like and take some of that makeup off so I can see your freckles.
