A perjorative term pertaining to a student or athletic team member of the pathetic institution that is Iowa State University. Note the similarity to the term "Assclown". The term is in reality a combination of ISU's mascot, the Cyclone and "Assclown." One might say that a Cyclown is the skidmark on the proverbial underwear of the state of Iowa.
Adam: you, my dear sir, are a God damn, no-talent, Cyclown!!!!!!!
