The best type of friend. He’s loving and caring and he’s super funny and will always be there for you. He’s the type of guy every girl wants to know and loves. After knowing him for a while you may start to catch feelings for him. He’s the type of guy you never want to loose because you love him so much ❤️🙄

Crush: hi😉
Me: omg he looks like my new reef😍❤️😂

"To reef", is a sailing term which means to lower or bunch the sails up in anticipation of a strong and dangerous wind.
It would require pulling on a rope which would have been made of hemp (oh yeah, same stuff, it made good rope as well) thus the terms "reef the sails", or, "reef her up", or even cowboy slang meaning to jerk harshly on a rope when team roping.
Reefer as far as convenience store Coca-Cola goes must mean a refill, hardly as colorful a term.
Talk about dumbing down.

Once the rope goes around its horns, reef it up and get your dallies in.

Reef is an amazing guy. He is very musically talented. He is usually very tall with brown hair and light brown eyes. He has a very large penis and can make you breathless in bed. He can take your heart away but once your heart gets broken by a reef you’ll wish you were dead. If you have a Reef in your life then never let him go you will regret it

I met a Reef last night😍
