2C4U

Someone who sends you 2C4U is "too cool for you." You're most likely to receive this braggadocious acronym in messages sent by family and friends, but don't worry! 2C4U is typically used sarcastically.

If someone earnestly says they're 2C4U, you're likely better off not talking to that person anyway. In that case, tell the person to get lost, and move on to a conversation with someone who appreciates you.
