bromantic period 

(n.) An extended period of time when one or more heterosexual males, void of female companionship, go on a road trip or other such life changing event in which all members create a special bond and pursue bromarriages or a bromance. Refer to the movie Butch Cassidy and the Sundance Kid. A very important period of all males' lives usually followed by a Renaissance period of plethora of facebook messaging, inside jokes, sharing of alcohol, pre-gaming, and arriving at parties together.

Aden: Hey Rich, why don't some of your buddies on our road trip to Mardi Gras?
Rich: Great idea! This bromantic period will rival Butch Cassidy and the Sundance Kid

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”
