Bob sounds like a Small Name, Big Ego.
All the blaming of others for Bob's own underachieving has shades of Never My Fault.
It's not so much Bob blaming others as it is them being a constant reminder that he sucks.
Kind of feels like a parody of Always Someone Better, where Bob's been doing fine coasting until Alice comes along with her adequateness and slight effort.
Overshadowed By Mundane
Rather than Bob being skilled and outclassed by the more talented Alice as in Overshadowed by Awesome, Bob is utterly inept and Alice has a perfectly mundane level of skill (or even lower than average), but the gap in ability is the same or greater than with Overshadowed by Awesome. Bob usually feels threatened by this, but gets no sympathy as it's pointed out his lack of skill is his own fault.
For instance, Alice runs a lap around a sports field, as does Bob. It takes Alice five minutes to do so, but it's still faster than Bob, who takes a quarter of an hour to finish.
Bob is a C+ student, Alice a B-, Bob calls Alice a tryhard.
Bob is a Casanova Wannabe who's asked hundreds of women out and got turned down every single time. Al has asked women out a total of five times in his life, got rejected twice, Bob hates Al as though Al was The Pornomancer.
Alice is a new hire at Bob's workplace, and starts unknowingly making Bob look bad because she's visibly outdoing him in basic tasks like being on time, cleaning up after herself, being nice to people, etc.
