Randy: Dude did you go home with that elderly couple last night?
Chet: Yeah, I went back to their house, things got pretty heavy we ended up finishing the night with a round of Rusty Yaks.
Or
Randy: dude you and Sarah were pretty loud last night in your tent.
Chet: yeah, Sarah was giving me a rusty trombone but on day 5 of camping things were pretty rank back there and she yakked, so we made the best of a bad sitch and turned in into a Rusty Yak.
