A combining of the expletive-laden labels dip shit and dumb fuck. This insult usually occurs when a person is so pissed off that in mid-insult he/she changes his/her mind as to what the insult should be. The result is a combination of dip and fuck, as shit and dumb drop off due to their unfortunate residence in the middle.
You're such a dip fuck! Those were my twinkies!
A really dumb person, who cannot be classified as a dip shit, but as a seperate class.
