Lewis diagram for OF+

A good way to think about stuff like this, is to imagine a possible synthesis for the given intermediate. One way of making this species would be to cleave the H-OF bond of HOF against it's electronegativity, that is, heterolytically cleaving the bond to make H- and [OF]+

As we are going against electronegativity, you get the idea that the intermediates are quite unstable, and so your structure must represent a reactive species
