knocker-upper

== English == === Etymology === By a regular pattern for (informal) nouns seen also in similar forms, such as fixer-upper and cleaner-upper; the sire sense involves an extra degree of wordplay, as an alternative surface analysis of knock (h)er up + -er is playfully apparent (who knocked 'er up?). === Pronunciation === === Noun === knocker-upper (plural knocker-uppers) Alternative form of knocker-up (person who knocks to awaken in the morning). (in coopering, a tool to hammer the top head of a cask into place through the bung hole). (informal, humorous) The male who has sired a pregnancy. Synonyms: sire, father, dad, daddy, baby daddy
