Generating from Birmingham, England, this word is another way to say the word "definiately". It was formed from the Tottenham Hotspur and England striker Jermain Defoe's first name, as many people say the word "defo" instead of definately.
Underrated af, the guy who has split personalities, and is WAY different when you meet him in person than online. Funny , but also mean in a joking way. He brings up random stuff at random times in parties and conversations. Jermain is a guy to leave you when he wants to, but in reason that he can’t express. Jermain is either short or tall nothing in between.
Jermain can be used as a singular noun for a legendary or at times classendary person. The noun Jermain is derived from the Spurs player Jermain Defo. Jermain is used to refer to people in the singular only, it is not a collective noun.
