Fehz
Fehz is someone who likes to see others get themselves into sticky situation whilst he/she is just on the sidelines watching. Fehz has to be right, he/she is never wrong. Fehz is typically someone with a poor immune system and easily finds themselves bed bound just from smelling a fart.
Don’t be a fehz and just watch, get involved.
You might be right, but you’re not ‘fehz’ right.
