stepbrotherson

The unfortunate relationship between a man and a child fathered by HIS father after the SON marries that father’s ex-girlfriend. The child would be BOTH the SON’s “brother” AND his “step-son”. Originating in Texas!

I’m going to visit my Son and see my LAST Son, or his StepBrotherSon.

STEMboy

A femboy who's obsessed with science. May have a pompous or STEMlord-like attitude towards others, but generally just nerdy.

1: My favorite character is Venti, and I can name every component of a particle accelerator!
2: What are you, a STEMboy?

Eskimo Stepbrothers

Similar to Eskimo Brothers, when 2 dudes fuck the same girl, but she is black.

Yo, me and Nick just became Eskimo Stepbrothers!

That's kinda cool, but still pretty fucking gross man.
