a mosby 

Telling someone who you are romantically interested in and who is interested in you as well that you love them, causing them to not feel any romantic interest towards you and freaking them out.

Telling a woman you're interested in and have realized you love at some point you love her, causing her to lose any of the obvious romantic feelings she had for you.

Same for a woman towards a man.

I.e. the exchange between Barney and Robin in How I Met Your Mother, and also the reason for the name itself - Ted Mosby from How I Met Your Mother.

"Tim just pulled a Mosby on Rachel"

"Oh God, he's never going to be able to get with her then. She was talking about how much she liked him just last week too"

The act of doing something completely ass backwards. Generally anything that involves an illogical choice or decision that would be viewed by anyone as retarded.
