I am certain that Bob went to his high school reunion all excited. He would get revenge on all his enemies for mocking him and not dating him..
But alas the people that so show up to those sort of things have their shit together. They have jobs, careers, and families. It's not like the movies. The bullies and the jocks don't get their just desserts. The best revenge is living well which as shown by bob's weight and anger issues, hasn't happened.
I am sure at one point he tried to explain to some random person that he is "kind of a big deal in youtube" to which that person replied that their 12 year old does the same thing and chuckles. That person would have not meant anything by it, but bon would have gotten really pissed and stormed out.
In the act of doing so, naturally half the room would suddenly remember who he was as this was his usual routine in highs school.
