Your mum gay 

Your mum gay is the ultimate response to when someone is being annoying or is getting angry with you.

You can add the "lol" at the end to give it that extra punch.

Your mum gay was also used by Pewdiepie in February 2018. But it was originally created by NFKRZ Bangerz in a Pyrocinical video when in a CS:GO match when someone said "Why did you do that" and he replied with "Because your mum gay" and after a eruption of laughter happened.
It has also been a running joke on NFKRZ's channel as he is also Russian and mocking people who can't speak English that well.

P1: WHY THE HELL DID YOU DO THAT?
P2: cuz your mum gay lol.

Your mum in a bag 

An insult originally coined in the mid 1700's by Anglo-Irish writer Jonathan Swift. The insult has no real defined meaning but It can be determined from context to essentially be accusing ones mother of being a possession. As was commonplace then and now many people carry their possessions in bags, thus the insult begins to make sense.

While not commonly used, the insult has begun to make an appearance on many social media sites such as facebook, instagram, imgur, youtube etc.

"I know your mother well. She's in a bag" or "Your mum in a bag"
