"lol-in" is a term associated with the act of someone moving all their chips into a pot with something very weak, vulnerable, or obviously beaten in a hand of poker. It's basically moving "All-in" with a strong dickhead factor.
"I saw Bob make such a lol-in with 7h2h on a board of AsKs4s10sJc 6 handed yesterday. What a fucking donkey!"
"Hah! Really!? Could he even SEE the board!?"

The term used that is slightly nicer than saying, "Now that just wasn't funny." Not to be confused with 'lol' alone, without a period.

A term commonly used on the internet when you're not really paying attention, or have nothing to say.
