FOB stands for fresh off the boat. Its used as a noun - "so and so is a FOB". A FOB is basically any immigrant. Most definitions here refer it to east asians but its not limited to them.
Most contexts seem to use it with negative connotation - that the person has not adjusted to western culture and that they should be ashamed of their customs.
Sometimes, more trivially, it's used in the following context: when you think you're doing something 'cool' (by the standards of your people), but youre not (by the standards of white people), you're being a fob.
It could also be used as an adjective: fobby.
