noun: portmanteau of "charter" and "retard". A misnomer referring to a Charter School of Wilmington student who displays zombie-like behavior in the hallways and excessive use of calculators for ridiculously simple math problems, such 2+2. These creatures typically have no others skills except that of math and science, and have no life.
Look at John. The only thing he knows how to do is use that fancy-schamancy calculator and name elements off the periodic table. What a chartard.
