Get the Prolly mug.
This is a colloquial version of the word "probably", in common usage in the upper Midwest, especially those areas of Wisconsin whose populations were drawn from German-speaking immigrants like Milwaukee and Madison. Definitely predates Internet.

Get the Prolly mug.
A spoken colloquialism that existed pre-internet, despite what many people claim.

"Prolly" is a clipped pronunciation of "probably"; compare with "g'day" as a clipped pronunciation of "good day", or "gonna" as a common spoken shortening of "going to".

Certainly non-standard, but not necessarily indicative of the writer's laziness. For some, writing in this manner mimics their natural speech pattern/dialect.
She said she'd prolly come over after she's finished relaxin' at the beach.

(spoken example) "I'm prolly gonna head down to Toranna {Toronto} for the May 2-4."

Get the prolly mug.
Literary colloquialism for "probably", most likely first used in print in John Kennedy Toole's Confederacy of Dunces, (1980), in the speech of one of the book's characters, the mother of the protagonist, Ignatius J. Reilly. The use of the word is meant to reflect the speech typical of white working-class residents of New Orleans, Louisiana.
That prolly is the reason he left in the first place.
