A pedestrian walking on dark streets at night often in dark clothing, with little regard to their surroundings. Antelope disregard traffic and safety guidelines. They tend to dart out in front of you out of nowhere, like deer. If you almost hit one they will become angered as if it's your fault they're practically invisible. Rather than gasping and saying "Oh dear!" upon sight, one should simply scream "Antelope" instead to avoid confusion.
Did you see that antelope pop up out of nowhere after we passed the store? Yeah he didn't even slow down, I almost hit him!
