The tOSU dislike comes from the fact that the tOSU FB fanbase have lots of internet trolls. Since PSU has joined the conference they are 2nd in B1G FB crowns & the FB series is still split but many internet tOSU FB fans are really disrespectful, worse fans ever. Older PSU fans know however that that is not a reflection of the rest of their alums etc. Since PSU no longer has Pitt anymore most PSU fans consider tOSU their biggest rival in FB. So beating tOSU at the shoe last year was a big deal in HV. But they don't fully realize that to OSU it is just another game in the B1G & their rivalry game is UM.
