<human>: Can you give me a shortened version of the text?

So my room mate has been hooking up with a girl for a few months now. When they want to have their 'fun time', he'll kick me out of the room, so to speak, and I'll come back later. At first it wasn't an issue, and I was actually proud of him, but lately its become obnoxious, as he'll request to use the room on a daily basis. I don't let him every day of course, cuz I've got shit to do, but they still do their thing more often than I'd like on the agreement that my room mate throws down money for my alcohal whenever their shenanigans are inconvienient to me.  It's still obnoxious, however, so I've decided to start subtely pranking him by setting things up in the room beforehand, but I need ideas on what to do. That's where you come in. Give me your best ideas, reddit!
<bot>: room mate is sexiling me multiple times a week. Give me ideas to troll him while he's doin the dirty.
