Rumor has it (I think I picked this up on TVTropes, maybe?) that someone made a creepy subreddit devoted entire to her feet that freaked her out and made her back off. Apparently it got popular enough that someone from the RLM media team and essentially asked what the fuck was going on, at which point the creators were like "Its just a prank bro, honest!" and apparently the pictures weren't even her feet. and promptly deleted the whole thing.
I have no info to back this up. Maybe someone who keeps this kind of shit can throw me some screencaps.
A more logical explanation is that getting together and watching stupid, terrible old movies nobody cares about while having way too much to drink is a really stereotypical "guy thing" to do. Generally if a girl wants to watch a movie with a bunch of guys or just her boyfriend, they're going to pick something that's actually not fucking garbage (depending on the movie taste of the chick in question.). Jessi probably just got bored with the whole thing and combined with dumbasses yelling "UGH SOMEONE ELSE ON MAH SHOW" like how literally 90% of the RLM fanbase reacts when anyone who isn't Mike, Rich or Jay is on just decided to back out.
