unfashionably late

Derived from fashionably late.
To be unfashionably late is to have missed, and gone over the time period (between 5-15 minutes) where you are fashionably late. While being fashionably late is recognized by the host(s), being unfashionably late makes you seem rude.

"Tom was unfashionably late for my party, what a dick"
