It's Cauc+Asian

If a coworker asks you how to spell 'Caucasian,' and you spell it for him, and he hears the first four letters right but messes up the rest, don't tell him that it's spelled "Like 'Asian' with 'cauc' on it." 'Cauc' and 'cock' sound the same out loud and you will never live this down. # LFMF.
