Insufficient Funds Syndrome. Usually a diagnoses will be performed by your bank, instead of your doctor. Symptons include, but are not limited to; Having to put all your groceries back at the supermarket, Hearing the cashier say, "sorry sir, but you cannot purchase porn and cigarettes because your card has been declined.", And the most severe symptom is having no life, no friends and definitely no girlfriend. Not all people with IFS experience these symptoms, but do not be fooled, this syndrome is not one you would like to contract.
"Dude, I went to the bank earlier and they told me I have IFS, how do I tell my girlfriend?"

"I'm afraid I can't #crackacoldonewiththeboys tonight bro, I have IFS."
"I really want a fidget spinner, but with IFS, my choices are limited to watching videos on YouTube about 11 year old kids who are already fidget spinning pros, when I know that I would be the best in the world if I just didn't suffer from IFS."
