IFS

Similar to IBS,Irritable Friend Syndrome can occur when a friend unexpectantly morphs into an obnoxious bitch, but you have known them too long to severe the relationship.
Help me! I have serious IFS with my best friend since 7th grade and I don't know how to tell her to shut the hell up without hurting her feelings.

Ifs

Idiot Freaks. All of those people with no common sense who act as if they know what they are doing. Who try to communicate with others, ie you and me , in an attempt to feel normal and part of the human race. You may not know if you are an IF, but you have surely been affected by one or more in your lifetime.
Ifs try to turn left from the right hand lane without a signal and then flip off the person who they cut off.
Ifs push an empty stroller in Disneyland and there is no child in sight.
Ifs read this on a Friday night.

IFS

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."
