BodyByMark is the channel this is from.
In my opinion, Mark is a scumbag, low life lunatic with possible stalker tendencies.
There was 1 recent video of a guy rushing to catch a train. He even told Mark that he was in a rush. That didn’t deter Mark. Looney Tunes proceeded to follow him and wouldn’t leave him alone.
The majority of reactions he receives are of disgust and irritation. These people are visibly uncomfortable around him and appear to be frazzled and nervous with his perverted questions.
I think he hovers over them and blocks their escapes until they answer his questions. I feel there is something deeply disturbing and unsettling about this Mark guy. He definitely seems like a true schmoe on the prowl for his fantasy file.
