Transcends all ur mum gay variations. They all cower in fear at the use of this phrase. If used against someone they will pass hell and go straight into the plane of non-existance, where nobody will ever remember you.

Brenda: ur sisters a mister
Chad: ur brother a mother
*Brenda instantly stops existing*
