The movie scene that Parker mimics is taken from "Love Actually" where actor Hugh Grant, in the role of UK Prime Minister, loosens the tie and dances to the song "Jump" by Girls Aloud.
The video is now being celebrated worldwide and English big star Tyson Fury comments, among other things, the clip with: "Haha, this was absolutely amazing" followed by several laugh emojis.
NFL player Xavier Su'a-Filo writes: "You have won the quarantine competition".
28-year-old Parker was a heavyweight WBO champion between 2016 and 2018 before losing his master belt to Briton Anthony Joshua. The New Zealander has gone a total of 29 professional matches and won 27, of which 21 via knockout.
