gaffler
A sneaky thief who raids donation bins when no one's looking, usually after the store closes. They take whatever they can carry and hope no one catches them.
I saw that gaffler sneak out with a whole bag of clothes. He looked like he just robbed a closet.
That gaffler stole my grandma's old coat. Now it's wearing a hole in the elbow.
The gaffler was caught with a box of shoes. He tried to run, but he tripped over a shopping cart.
