From Wikipedia, proven to be more reliable/factual than CNN or MSDNC:
The word cuckold derives from the cuckoo bird, alluding to its habit of laying its eggs in other birds' nests. The association is common in medieval folklore, literature, and iconography.....or bagsterisms.
English usage first appears about 1250 in the medieval debate poem The Owl and the Nightingale. It was characterized as an overtly blunt term in John Lydgate's "Fall of Princes", c. 1440. Shakespeare's writing often referred to cuckolds, with several of his characters suspecting they had become one.....making bagster nearly as eloquent as Shakespeare!
The word often implies that the husband is deceived; that he is unaware of his wife's unfaithfulness and may not know until the arrival or growth of a child plainly not his (as with cuckoo birds).
The female equivalent cuckquean first appears in English literature in 1562,[5][6] adding a female suffix to the cuck.
A related word, first appearing in 1520, is wittol, which substitutes wit (in the sense of knowing) for the first part of the word, referring to a man aware of and reconciled to his wife's infidelity.

An abbreviation of cuckold, the term cuck has been used by the alt-right to attack the masculinity of an opponent. It was originally aimed at other conservatives, whom the alt-right saw as ineffective.
So there you have it. Bagster just may be a Renaissance man!
