Bysyn Bhicken Buggets 

Bysyn is a new sexuality.

Being a Bysyn Bhicken Buggets means that you are self producing, and only reproduces with themself on a friday night eating chicken nuggets. This sexuality only exists in Minnesota, and it wishes to be called "zhe" or "sklurm" or "splooge". Only 0.001% of the population has this. Incredible that I could meet this person!

hey bro, be honest with me... Are you a Bysyn Bhicken Buggets?

yeah bro...

It's okay. This is 2019. We accept you fam.
