boop-swoop
When one person, male or female, successfully gets someone to leave their current significant other for them. Could be part of a challenge with friends.
Just found out Stacey has a boyfriend, I'm going in for the boop-swoop.
Boop Swoop
When you hate being booped but people think your adorable anyways, so you move your head when they try to do it.
I boop swoop my boyfriend about 10 times a day.
