Using corporate funds to visit a client that you really don't need to see. The real reason for visiting the client is to explore the area, visit a friend, try the food scene, or some other personal reason not associated with work. Your boss is unaware of your true motive and believes you are actually conducting work.
Salesperson 1: "Jim is going to Hawaii to visit his client next week."
Salesperson 2: "Bullshit. Jim's client there is tiny. That's just a boondoggle so he can surf all week. I bet he only goes to the office once."
(verb) This occurs when you're in a school restroom and someone's pants are completely down and their ass is fully exposed, and then you decide to slap their bare ass cheeks.
Example: (Tyrese has his ass out) SMACK! "Damn bro you just boondoggled his ass."
