Step Second Cousin

A second cousin that isn’t blood related even though second cousins are barely blood related.

Man, I just found out that my second cousin isn’t my second cousin. She’s my step second cousin cause she’s not blood related to me.

Half Second Cousin

A second cousin that only shares one great grandparent instead of both great grandparents.

It’s complicated to figure out how a half second cousin is related to me.

Third Cousin

A cousin that shares a same pair of great great grandparents. Most people never met their third cousins. There’s plenty of people that never even met their second cousins.

I’m meeting my third cousin tomorrow who I’ve never even met before.

Cousin

Someone who always gets on your nevers, in your beeswax and likes to get the fair share in everything.

OR

Someone you can always trust and is not a snitch. Can be hella lit sometimes.

First example: Bro, I was trying to go to this hella lit Halloween party but my dumb ass cousin had to tag along.

Second: He's coming to the party with me Stacey not you he is my cousin.
