J

J is an abbreviation of "joint," which is a rolled marijuana cigarette. Drug users or dealers looking to get high or sell some of their "product" commonly use the abbreviation.

You might hear j in real-life conversations or see j in messages online or in texts. For example, a teenager may text his friend, "You got a j for me after school?"

While j is often used to disguise drug activity from parents or authorities, it's not very effective nowadays since it's so well known. Some other slang for marijuana includes tree, dank, mary jane, and GSW.

J is an abbreviation for when you want to denote a comment as joking. It means that the sender is not serious and is just being playful, humorous, goofy, etc.

You will likely see J online in messages (including DMs and emails), on social sites, or when texting. For example, your friend may comment on your Instagram post, "Think you can get a refund for that haircut? J." Or, you may text your friend, "U hungry? I think I could eat 3 burgers. J."

J is just one way to tell a person you are joking. Other options include JK, JJ, and joshing. People may also write J as <J>.

In basketball, j is short for "jump shot," a type of shot involving jumping and shooting simultaneously. J is a common basketball slang term that players, fans, and commentators use.

There are several types of js in basketball. Some examples include pull-up js, which is when a player stops quickly and shoots a j, and running js, which is when a player is running and jumps to shoot all in one motion.

You may also hear people refer to their Jordans (type of shoe from the popular Nike Air Jordan brand) as Js. So keep that in mind when someone says they are jealous of someone's Js.
