ur niece smell like cheese 

Instantly crucifies any person unlucky enough to be struck with this fatal blow. ur mum gay, ur dad lesbian, none of those hold a candle to the sheer power of this.

The year is 40000 CE. War has been waging against Joe and Carl for ages. The universe is at its last bit of power. It cannot hold for much longer.

Joe: ur family tree LGBT
Carl: I’m sorry, old pal.
Joe: wha-
Carl: ur niece smell like cheese

Joe instantly dies. The universe collapses in on itself.
