your sister a mister is possibly the worst insult ever created. It will destroy an entire dimension whenever it is used. Another language had to be made to create this phrase, and this is the rough translation. Calling someone's sibling trans is easily worse than Your mom gay, Your dad lesbian, Your granny tranny and Ur grandpap a trap are hardly insults copared to your sister a mister.
