A Restroom Shaker can be either one or two people. If one, then a Restroom Shaker is jerking off so hard that the whole row of stalls is shaking. If two, then Restroom Shakers are two people having really hard-core sex that they make the whole row of stalls shake, attracting a large crowd outside of the stall they're in. This reaction from the public often causes the Restroom Shakers to never commit again, therefore passing their title of Restroom Shaker into somebody else.
Man: "Omg, it sounds like there's a Restroom Shaker in there"
Woman: " Yeah, sure does... Let's go check it out! "
