An ultimate sideman, like as much as those fishermen that followed Jesus all the way to the top of a mountain and gave him fish for his approval. A fish boy would follow you to the ends of the earth just for you to acknowledge them.
Friend 1: Wow! Tom is such a sideman
Friend 2: I know right, he's a fucking fish boy
Tom (the fish boy): Hey guys, what you talking about? you doing anything this weekend? can I come? be my friends?

A boy who is holding a fish in all of his profile pictures, all he talks about is how great the water was and how big a fish he caught. Usually accompanied with a comment like " i love fishing". Wears sun glasses on the back of his head, and fishing t-shirts. Will love going fishing more than he loves you.
wow, look at this picture of fish boy and the marlin he caught on sunday!

A man who wears make-up, giving him the smooth skinned appearance of a fish.

Should be spoken in a loud tone of voice, similar to the name calling heard in British football grounds.
"Why does you skin look so silky smooth, blood?"

"I think he's wearing make-up."

"FISH BOYYYYYY!! "

Fish boys are typically highschool aged Caucasian heterosexual cisgender boys. They have blonde to brown hair like an ugly short/mullet haircut with a orange tinge to their fake tan skin, just like their idol, Donald trump. They wear Florida/pro bass shop merch and love fishing. They wear buttonup shirts, khaki pants to dri fit shirts with sweatpants/ basketball shorts, with sport shoes/slides with socks. They are quite sporty, which makes alot of them to be in good shape. They tend to come from conservative/republican families, are one themselves and hold traditional views. They also tend to have low IQ and tend to be unaccustomed to anything that isn’t in the south. They are racist(use of offensive slurs and offensive stereotypes), homophobic/anti-lgbtqia, sexist and misogynist. They are also loud, agressive, obnoxious, and callow. They don’t pay attention in class because they play unblocked games often. Fish girls exist too and are pretty much the same.
“Ew do you see that fish boy? He said that all Asians look the same. He also didn’t know Indonesia was a country and said that Mongolia was part of China . Poor guy.”
“Ew, that fish boy just got more red like a tomato from rotting In the sun. Now I kindof miss his old orange spray tan.”
“Ew, why did he cut his hair like that? He is really disgracing the mullet haircut. It looks absolutely hideous!!”
“Yo did you see that fish boy?? He literally kissed his boy best friend and said it was a “joke”. He’s literally gay. I can feel it. Classic closeted internalized homophobia. Just wait 10 years I betcha it’ll happen my gaydar don’t lie.”
“Did you hear about that fish boy? He grabbed his bois butt during class as “joke” and got a referral lmaoooo and all his friends are calling him gay now which he denies ofc”
