What it means
A whippersnapper is a cheeky young upstart, usually said by someone older who's had enough of a kid or twenty-something acting like they've cracked life already. It's got that grumbly, old-school bite to it, but often with more eye-roll than real fury.
Usage examples

"The new manager is a right whippersnapper, fresh out of uni and already rearranging a department he started in last week."
"Some whippersnapper half my age tried to tell me how to parallel park, I have been driving since before he was born."
"Look at this whippersnapper trying to explain taxes to me when he's never filled out a proper form in his life."
"Some whippersnapper in the office called my method outdated, then spent an hour fixing the mess he'd made."
Where it comes from
Whippersnapper has been in English since the late 1600s. Early forms include whip-snapper, used for a flashy or idle young man with too much swagger for his own good. Over time it settled into whippersnapper and kept that same grumbly energy for a young person who's cocky, cheeky, and talking above their station.
