1. The expression of not wanting to deal with
something at the moment, or finding certain things unappeasable.
Origin: Derived from the phrase "Too Far" which had become too long to say due to laziness, leading the use of just the
two letters "
T" "F", which also, after so long had become two syllables too many, thus eventually leading to "Tiff."
It is often used to replace phrases such as; "Screw that," "Fuck this," "forget about it," etc.
Nick: Hey man, let's go to the library and get our study on.
Carl:
Dude, tiff that.
Girlfriend: You never spend enough time with me!
Boyfriend: Tiff this relationship.
