Combination of the word double and the phrase lol, referring to something too amusing for the mere lol and thus calling for the more powerful "doublol". Used most commonly shortly after someone has already replied to a previous statement with the less powerful lol.
Brant: So, I saw Alyssa and Josh earlier, I guess they're dating...
Matt: LOL
Brant: And somebody told me they were even engaged too...
Matt: DOUBLOL!!111!1
Matt: LOL
Brant: And somebody told me they were even engaged too...
Matt: DOUBLOL!!111!1
