First Person Gaming style developed by Ubi, where the player is always moving and controling the entire map or playground. Combined with "aim" this is a powerful technique
A person who is always around, usually with spiky hair-hence the porcupine. Every corner, every hallway. There is no escaping the uncomfortable eye contact and awkward conversation intrusions. Wherever you go, there will always be a ubiquitous porcupine that you will never escape from.
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 porcupinequills 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.
