In the proofreading
business, a document that is full of typographical errors,
aka, “typos.” The expression is a play on the concept of the so-called universal blood donor: type O being the blood type that can be donated and transfused to anyone regardless of their blood type, a “universal donor” document is … chock full of Type
Os.
Chad, take this universal donor back to your
desk and
fix all the typos and misspellings, jeez.
