Someone who either cancels plans at the last minute or just flat out bails and doesn't show up for a party etc.

If someone does this, it is said that they "CUT YOUR BALLS OFF." So a ballcutter is someone who cuts your balls off.
"Hey did Tanya show up at your party?"
"Nah, dude. She's a ballcutter."
