English slang which can mean feeling poorly or can describe something as useless or unfit for purpose. So if someone says they feel like shit warmed it means they are feeling extremely unwell or under the weather. But if it is their opinion of a device, person or product, it means that the device, person or product is a total WOFS.
Wammer is a term used for a highschool and\or college party with more then 75 people and lots and lots of beer,alchol,girls,drugs. Not a sausage party.
