Oh, dude, you're really into those three-letter acronyms, huh? Well, there's "OMG" for "Oh my God," "LOL" for "Laugh out loud," and "BRB" for "Be right back." Like, they're everywhere, man. Just remember not to overuse them in texts or you might sound like a robot.
a three letter word is bug. Three letter words ending with the letter g are bug and hug.
That's usually "col." Check the "g."
