A pejorative retail slang for window shopping customers (usually female) who like to try on numerous amounts of clothes and shoes but ultimately end up not buying them for a random pointless reason.
There are two types of hush puppies:
A Hush Puppy is a regular customer who has manners and may thank or apologize the sales associate for the inconvenience.
The Hush Bitch is a mean and/or rude customer who do not show manners. They will leave the store without word and will usually do it when the sales associate is at the storage looking for a shoe they asked for.
Both versions are equally annoying. Hush puppies and hush bitches alike are the mortal enemies of sales associates.
Sales Associate A: Dude, I had the worst day today. A Hush Puppy came to the store, asked for 5 pairs of shoes, and then said she didn't like them and just left.
Sales Associate B: Man, that's nothing. Today, a Hush Bitch asked me for 3 pairs of shoes in 2 different sizes, then just left when I was coming back for the other sizes.
