Get the JMFS mug.

How do these people or businesses do this? They have no qualms misrepresenting you. They source, sell or represent you, your brand or your products in a self serving manner. Their goal is not to partner, but to put you out of business. Synonym: trainshipper, anti-partnership, unethical, dirty, douche canoe, bad people, bad business practices, dicks!
"We can't sell our stuff there, they are a bunch of JMFs." Or, "Do your homework, that retailer might be a JMF." Or "Did you see what that Janky Muther Fucker did in Greece? He just screwed you, royally."
