I recently (last night) gave in to temptation and opened up my own fictional fratboy twitter account alongside RedSpkScott's. My character's a beefy wrestler named Mitch, and he likes to spank his fellow brothers. ;]
It'll work the same as Scott's. Follow me, and I'll follow you back. Aim a tweet in my direction (or even make up your own character), and I'll reply in-character. Let's get all the spank-fans to do some experimental RPing!
