Simply the ultimate word. A perfect mixture of the words TTYL LOL LMFAO OMFG and GTG. They combine together to create the perfect word where each word within it shares a letter. No one alive except Chuck Norris can handle his word
Ttylolmfaomgtg is a combination of talk to you later, laughing out loud, laughing my fucking ass off, oh my god, and got to go. It is normally used when someone has said something really funny or interesting and you would love to continue the conversation but you really have to go.
