Your cousin a dyke 

A phrase that has to be used as a last resort, as it is extremely dangerous. The insult to end all lower insults like "your mom gay" and "your granny tranny".

John: your mum gay
Carl: QUIET
John: ha, your granny granny
Carl: your cousin a dyke

Nothing more is heard as the very fibre of the universe is rended apart and Kermit the frog gets reborn as a large giant powerpuff Elmo.

ur cousin be fussin 

The worst insult of all time.

Bob: You're mom gay
Steve: Your dad lesbian
Bob: Your granny tranny
Steve: Your grandpap a trap
Bob: Your brother a mother
Steve: Your niece obese
Bob: Your family tree LGBT
Steve: Don't make me do it.
Bob: Do it!
Steve: Your cousin be fussin
(Bob then explodes, barely leaving Steve alive)

Ur Cousin 

Another very bad variation of ur mom that is generally used when speaking about incest but can also be used in many other situations.

Warning: using this variation of the common phrase "ur mom" may cause confusion due to it's unpopularity.

John: hey bro, what's up?
Dick: ur cousin

John: what?
