Bio

A slang term for bathroom, but actually comes from the word "biology," which refers to the natural process of having to go to the bathroom; understood in gaming settings to mean someone is taking a bathroom break.

A gaming term used in StarCraft; most often refers to Terran biological units such as Marines and Marauders.

You can use BIO to taunt someone online or in text messages when ready to battle with them. It stands for "bring it on," which is another way to say, "give me your best shot."

Where did BIO come from?

The phrase "bring it on" became popular in the late-1990s, peaking in popularity when a movie about competitive cheerleading by the same name was released in 2000. It was shortened as "BIO" when people began chatting and gaming more online in the 2000s.

When is BIO used?

Gamers may use BIO right before or during a competition to taunt their opponents. Games in which you may see BIO include WoW, LoL, DnD, Fortnite, COD, and DotA.

Others may use BIO in texts or on social sites or chatrooms when getting pumped up for a challenging exam, big competition, or another nerve-wracking event. In these cases, they are probably experiencing an adrenaline rush or the effects of steroids and may be easily excitable, so watch out.
