look up any word, like smh:
When you post something to a social site e.g. facebook, twitter; and you regret it after a few seconds or minutes, but are too lazy to remove it. Or you just want to know the response that it will get, but eventually regret ever doing so.
I posted something onto my facebook without looking at Urban Dictionary first... and now I have postal regret.
