Ok, I say:
Duh! when someone says something stupid or something that I already know
You ain't nothing but a skanky hoe! I say it in a really silly voice as like some sort of "cut down" or something
It's just a stupid inside joke between my hubby and me
'N Stuff 'N Stuff I tack this little phrase onto the end of most sentences when I'm feeling goofy. For instance, if someone asked me what I did last night, I would say, "I watched TV 'N stuff 'N stuff."
What do you think I am? Some sort of idoit or something? I say this in a Napoleon Dynamite-like voice when someone tries to tell me what to do and I already know how to do it.
Oh, and I REEEEEEEALLY overuse quotes from movies like:
Napoleon Dynamite (i.e. "I wish you would get out of my life and shut-up.")
Old School (i.e. when someone asks me what I'm doing this weekend, I'll say, "Well, um, actually a pretty nice little Saturday, we're going to go to Home Depot. Yeah, buy some wallpaper, maybe get some flooring, stuff like that. Maybe Bed, Bath, & Beyond, I don't know, I don't know if we'll have enough time.")
And my latest favorite,
Talladega Nights (i.e. "Chip! I'm gonna come at you like a spider monkey!" and "I'm all jacked up on mountain dew!")
