Spanish word for flipflop/sandal/slipper. It's what Hispanic/Latino parents (usually mothers) use to beat their child's ass when they've had it with their misbehaviour.
And don't even try to run, they can throw that thing round a corner like boomerang and if you manage to run out the house then don't expect to be allowed back inside without getting twice the original punishment.
Hispanic/Latina mother: *child's name*, GET OVER HERE NOW.
Kid: Shit, I can already feel la chancla getting spanked round my ass.
A flip-flop, slipper, or slide used as a dual use weapon (can be thrown or used for a direct hit) by latina females when angred by their boyfriend/girlfriend/husband/wife/whatever else, children, or a friend.
Latina: Talk back one more time and I will get la chancla.
Child: *talks back*
Latina: Estoy recibiendo el chancla! (I'm getting the chancla)
Latina: Beats childs ass for being a little bitch
