MABATE - A word that started as a way to describe the act of touching

A word that started as a way to describe the act of touching yourself, but now it's just a loud, obnoxious shout that everyone hears and does too.

'I said MABATE and now the whole bus is doing it.'

'MABATE was my morning routine and now it's my life.'

'My dog said MABATE and now I have to do it too.'
