When there’s 3 or more guys watching a girl pleasure herself and one guy gets the party started by whipping it out.
Guys: What is Meg doing on the floor?
Trev: Idk, but I feel a Walledagger coming on!
“Bagged Up” is a phrase that you use when you have a decent or comfortable amount of money on you or in your bank account on a short term basis.
Can also be used to refer to having a good amount of pretty much anything you see valuable at the time.
“Just wait. Come payday, I’ll be bagged up again.”
