Fit spoilered so I don’t ruin AssignedEva’s week, lol:
It's too late, I have an itchy trigger finger.
From head to toe we've got a diamanté choker, a Spiderman (well, Venom) crop top, a bedazzled belt, denim cutoffs, a garter belt with stockings and those stupid Demonia boots. I can't even say "it looks like he got dressed in the dark" because even if it was pitch black you'd be able to touch those items and feel they don't go together. It looks more like he has a Cher Horowitz style wardrobe planner and accidentally set it to shuffle.
Course, what’s the over/under that he made this girl all up?
50/50. It's a zero stakes lie - he got rizzed by this girl on his "way out" from the venue, so assuming he went with a friend he can say "oh she came up to me when you were ahead of me in the cloakroom queue" or whatever, and then he gets to telegraph that he got approached by a hot woman because he's
so hot and also that he's going to Los Angeles to work on his stupid vampire project.
On the other hand, it was a Kim Petras concert. It's not inconceivable that there was a trans woman there that was a huge fan of PhilosophyTube and thinks Abigail is super hot (and to be fair it was dark and everyone was probably drunk) and approached him with an AGP-fuelled confidence that read as rizz to Ollie. And in that scenario? This would mesh with braggadocio and tendency to dangle his girlies in front of his audience to show off how sexually in demand he is (albeit with emojis posted over their faces).
The funniest thing is he mentioned he had a Valentine's Day date.

so saying he's going to text a stranger he met at a context is underlining that either he didn't have a Valentine, his Valentine didn't work out or simply that he went on a tinder first date on Valentine's Day for something to do.
