Kofiing is where a person will go to their boss explaining they have finished their work with the hopes of going home. Then said boss will pile on additional work. May also happen when asking your boss for clarification of a job or assignment.
"I just sent an email explaining I'd be done with the job by COB , so they kofiied me with another job assignment"
"I just went to say good bye but they are kofiing me with another job"
