"Hey dude, isn't that your sis--"
"No chance, bro."
"Huh?"
"Man, your dad just called your sister had a car cr--"
"No chance, bro."

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.
