A small, large, or huge cluster of customers who seemingly know each other and will converse for what seems like hours in an aisle of some retail establishment. A cluster of people blocking access too and from either end of an aisle.
Hey Jerry, those people have been in aisle three for like 30 min. That's totally an aisle herd

Jesus Christ another aisle herd, I just want to yell at that gaggle of customers and tell them too fucking disperse.

Man that aisle herd has been standing there for what seems like hours. I can't work around them when they do that and they are so rude.
