This is a combination of the two words Problem and Bother!
I was doing an interview and when the interviewer said "thanks guys" my friend said "No problem". So i went to say no problem but then the word bother came across my mind so i said..."No Probother"
"Thats no probother"
"Now thats going to be a probother"
Presobe is a cross of the terms presume and suppose!
The 'b' acts as a mutual difference between the two which creates a mutual hatred of the letter, thus causing the two to connect in unhappiness and to form a new word of confusing nature!
I created this word during the formation of a sentence which involved the saying of the word "hi" to someone I didnt want to talk to! I had jumbled the words and formed this awesome singular.
"I presobe we could go over and say hi"
"I presobe that wouldn't be an awful idea"
