Turkey Dump???

[Captain Tennille]

Ever committed this?

The Turkey Dump:

"When a student returning from college breaks up with their significant other from high school (usually due to another relationship at college). So-called because it traditionally takes place over thanksgiving break, the first time most students return from college."

has been extended to mean "terminating an undesirable relationship before the season of family get-togethers begins, thus avoiding uncomfortable situations and avoiding costly gift-giving."
