Sustomer 

When someone is suspicious about what you’re saying to them. Will they or won’t they buy what you’re saying?

Brad: “Hey, did Jenny believe you about last night?”
Chad: “I don’t know man, she’s being a real Sustomer.”

Sustomer 

A customer of insurance who is almost certainly attempting to commit insurance fraud

Pet Insurance Rep: "We're trying to get medical records, but this client is claiming the pet has never been to any vet; though the pet has been spayed and is up to date on vaccines, and they mentioned seeing a vet in a previous conversation"
Insurance Adjuster: "I found the medical records, looks like they asked the clinic not to send them to us and didn't want us to access them because the pet has several pre-existing conditions that they've made claims related to."
Rep: "Hmm.... sounds like a Sustomer to me!"

suctomer 

1) A really bad customer, usually with "I'm always right" attitude.
2) A sucker.

That suctomer of yours called back. She still wants free shipping to Hong Cong, and she's being anal retentive about it.

I just sold him the car at 200% over market rate. Heh, suctomers.

suctomer 

a customer who really, really sucks.

a customer who is Not Right.

someone who tries to scam an Etsy Seller.

"I had a suctomer who tried to claim that I didn't send my product, even when I had a delivery confirmation, time and date stamp from the USPS, and the package was Insured. They were just trying to get something for free. Effin' suctomer"

suctomer 

The most pernicious and unfortunately, common, kind of customer, usually found frequenting retail environments for no other reason but to harass young and inexperienced, teen-aged employees. Sometimes found online badgering telemarketers for long periods, but in this case, their role is mutual as lower life forms.

Oh my God, dude, here comes that suctomer from last week who said I messed up his order but it was exactly what he ordered. He's not a customer; he's a suctomer!
