Someone you fall in love with without even knowing it. They are a person that is always there for you, which makes you feel important. They are a person that is trusting, which makes you feel safe. They are a person that cares for you, helps you, loves you. Which makes you, you guessed it, fall in love with them. Some boy best friends are in love with you too, but some aren't. This person will hurt you without knowing. You will remember their smile, laugh. How they talk, how they move their lips, how they find every little thing funny. it just makes you love them more, but hey, you can't help it. It's okay, I can't help it either.
Someone: "Are you guys dating?"

Me: "No... that's my boy best friend.."

A boy best friend will be there for you, someone you can tell everything to. He knows the difference between “I’m fine” and “I’m great”. He knows when something is wrong and won’t stop asking until you tell him because he doesn’t want you to feel that way and want you to be happy. He will say goodnight and good morning every day. He’s going to tell you if a guy isn’t good enough because he doesn’t want anyone to break your heart or hurt you in anyway. He wants you to stay you and not let a guy let you down. A guy best friend is someone who tells you everything every little detail. He’s going to tell you all the guns he has in his video games his collection of shoes, and his tricks he can do. If he does have a girlfriend he will make you guys best friends no matter how jealous she seems because it’s the two girls he cares the most about, and at the end of the day even if he doesn’t say I love you inside he does and deep down you know he does.
Are you and Justin dating? No way he’s like my brother hes just my boy best friend

boy best friends are they best. they’re sorta like your boyfriend but like ur not. you eventually date but not u. u guys end up catching feelings for eachother but no one knows yet. a boy best friend will give u their sweatshirt will wear ur scrunchie. they will cuddle u. they will always be the first person there when u need them and always be ur shoulder to cry on. they’ll do face masks with u and play fight. everyone ships u guys but u guys don’t acknowledge it yet. a boy bsf will give u piggy back rides and all and treat u like a bf. they’ll always be there

Something you don’t want to be but something you don’t want your gf to have either. If she calls you her boy best friend then there’s a good chance like 60% chance that she don’t want you. She’s probably using you for validation or emotional support. However that 40% is where things could go bad if your the bf or good if you are the boy best friend. If she has a man and she calls you her boy best friend then there’s some hope she wants you. Chances are if her relationship is bad then she’s lowkey into you. Especially if she’s FaceTiming you, hanging out with you privately, and complimenting you or being extra nice to you then you can pretty much guarantee she wants you. However if you are the bf, then be careful her “boy best friend” might be someone she’s smashing on the low. Look out to see if they FaceTime often, hangout a lot, and are intimate or unusually friendly to each other.
She had a boy best friend so I ditched her. She’s now with that mf, but I got with her best friend last night at the darty.

A boy best friend is a boy who is a bestfriend for a girl and should always be there for you like a normal best friend:someone to laugh with,someone to smile with,someone to talk to whenever you want, someone who you trust and can tell any secrets to,someone to just make you happy

If your boy best friend hasn’t got at least three of these qualities he best to be done with 💙🤞💯
‘He’s my boy best friend:he’s kind trust worthy, honest,funny and has always been there for me since day 1’
