An Ubiquitous Porcupine is someone who is always annoyingly close. They're someone who you have way too much awkward eye contact, accidental run ins, and conversations but ins with. Typically, the U.P. will have annoying spiky hair that sticks up like a porcupine quills does. The U.P. just always seems to somehow appear wherever you decide to go, no matter how unlikely it is that they should be there.
