An informal variant of 'jerk', adding the '-o' suffix common in American slang to denote a person of a particular type. Used to describe someone obnoxious, inconsiderate, or socially offensive. The '-o' ending makes it sound slightly more contemptuous than plain 'jerk' and carries a mildly retro Americanism feel -- the kind of word you would hear in an 80s teen movie.
Some jerko cut in line and acted like nobody noticed.

Jerko is a mildly intensified version of jerk — the -o suffix adding a slightly cartoonish or retro flair to the insult. It means someone who's being obnoxious, inconsiderate, or just generally difficult to be around. It's not the most devastating insult in the arsenal; it sits comfortably in PG-13 territory, useful when you want to express genuine frustration without committing to anything harsher. The kind of word that sounds more 1980s than 2024, which is either a drawback or its entire charm.
He cut in line and then acted surprised when everyone called him a jerko.
