It sounds OK to me, but I also agree with Rosco's suggestions.

My impression of the term "roast" is that it describes an extensive series of insults and criticisms aimed at a single person (either seriously or as a joke). If you say that someone's friends "roasted him" about his new haircut, I imagine that all of his friends gathered around and made fun of the haircut to amuse each other, for at least several minutes. A "roast" primarily refers to a type of comedy routine in which a comedian comes up with many different ways to make fun of someone -- there's a Wikipedia page about it here, which I think will help you understand the other meanings as well: https://en.wikipedia.org/wiki/Roast_(comedy) I usually think of "roasting" someone as being a bit like a comedy roast. The person is subjected to an extended series of jokes or insults, rather than just being teased or laughed at in a casual way.

Take it to the urban dictionary, bro! https://www.urbandictionary.com/define.php?term=Roast Www.urbandictionary.com Great place for definitions of slang, as defined by those who use it! Felicidades!

I see the second sentence as very typical among friends. Roasting each other. The first sentence is maybe a little less common. Roast as in “make fun of” is typically casual / informal.

It seems odd, or unusual. I'd say for rival football fans "I laughed at, or mocked, or teased" You''d tease someone about their haircut, or make fun of.
