1. adv. - shortened variant of "probably"; in all likelihood; likely. Typically used online.

1. You should prolly used "prolly" only in instant messaging. Using it in real life sounds kinda lame-o. But I prolly won't follow this rule anyhow...

Usage Notes: Using "prolly" and other forms of internet slang do not make one an idiot, unlike many of the arrogant people here have established. It is used simply because it is quicker to type "prolly" than "probably".

Obviously a shortened word for 'probably' now used in internet conversations. Before the advent of this usage, it was commonly used in southern U.S. states in particular Texas as common vernacular and does NOT indicate laziness but dialectal and regional verbage.

Using 'prolly' is not a sign of idiocy or laziness but apropos savoir faire, subcultural quirks, accents and mannerisms just like many other phrases that come out of regional places.

Just think Pigeon English in Hawaii, Brooklyn slang or English/British expressions....we all got 'em!
Y'all prolly think I'm dumb for using this but it ain't so. I just wanna get to the point faster without havin' ta use so many goddamn letters! ;D
