A "fuck boy" is someone a girl knows is just good for sex and nothing else. He's not to be taken seriously in regards to any type of serious commitment and the tell tale signs are usually quite obvious. The term "Fuck boy" tends to have a derogatory from scorned women who could not differentiate a "fuck boy" to a "prospect".
The skank finally cleaned up her act and was looking a serious relationship; karma bamboozled her with a merited fuck boy and she reverted back to her old ways more empty than ever.

The newest person to a work place or a team. Someone that is out of the knowledge loop. Especially in a training environment. If you have to ask what a fuck boi is you just might be one.
