Romantic Lame Duck Period

When you have committed to plans with a girl that you are not romantically interested in and therefore feel like you are not able to pursue a romantic relationship with anyone else until that commitment is fulfilled.

Typically in reference to a homecoming or prom type event.

“Hey man are you gonna slide on Hannah?”

“Dude I can’t until after homecoming cause I told Jenna I would go with her and I don’t want to look like a douche”
“Dang man, you’re really in a romantic lame duck period”
