Basically like lashing out , but picking on the smallest things.
An example of "Rashing" someone is by correcting your friends grammer and punctuation , like when she asks you a question but puts an exclamation mark at the end of her sentence .

An unwanted person following you or a group of friends in order to try look popular, but failing to do so and getting no attention or respect from the group. Usually walks behind the group and doesn't talk at all.
Liam was totally rashing on our group yesterday, it was fucking annoying!
