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".
