rubber peter
n. A dildo. A peter made of rubber.
In a classic "Brady Bunch" episode, Alice gets Peter to help her move a rubber tree plant into the bedroom, to get it out of the way so she can vacuum. They accidentally get locked in, and call to Bobby for help. He can't get the door open, so he runs to find his mom, and when he finally does he's out of breath and all he can get out is, "Mom...Alice...in the bedroom...rubber...Peter." And Mrs. Brady thinks Bobby has seen Alice masturbating with a rubber peter. Mrs. Brady screams, "Jesus Fucking Christ" and goes running off to the bedroom and kicks down the door. When she realizes her mistake, they all have a good laugh at it. This was the best Brady Bunch episode ever.
