skooba, or better known as S.C.U.B.A is Self-Contained Underwater Breathing Apparatus. Pretty self-explanatory is it not?
See how the first letter of each word spells SCUBA?? Pretty clever huh? Well since SCUBA is acronym and therefore already taken, generally speaking. I decided to add a little of my own wittiness and spell SCUBA (the acronym) s-k-o-o-b-a (a non-acronym, generally speaking. Oh and also noticed that I used all lower case characters,save the "S", as well just to further prevent any confusion). So, even with my best efforts to prevent any confusion inadvertently created some. Pretty ironic. I'm sorry if the tone of my response might sound condescending and sting a little, but please, if you are going to ask a question such as "what is skooba?" that is remotely as retarded as the movie you named yourself after do us all a favor and think before you speak. Didn't your mama teach you anything?? So to answer your acronym-containing question, that's What The F*ck that is!
