What does BOU stand for in MMORPG?

Bind on use

When playing MMORPGs like World of Warcraft, gamers often use the term BOU, which stands for “bind on use”. It’s a lot like another term used in these games, BOE (bind on equip), but BOU is specifically about items that are used, instead of items that are equipped.

So, what does this actually mean in game play? Let’s take the example of small pets in World of Warcraft. If a player has a small pet that they haven’t used yet, they can trade it or sell it to other players. But once they’ve used that pet, it’s a different story.

Using the pet means it’s now bound to the player. They still own it, but they can’t trade it or sell it to other players anymore. They can, however, sell it to NPC vendors. So, when you hear BOU, just remember it means an item is tied to a player once it’s been used.

Example for using ‘BOU’ in a conversation

Hey, did you see that new pet in WoW?

Yeah, I did! It’s so cute. Is it BOU?

Yes, it is BOU! So if you haven’t used it yet, you can trade or sell it.

Got it! Thanks for explaining BOU to me.
