That is a chant people sing between verses of the hit song from the 60s, "Mony Mony". Billy Idol covered the song and took it to #1 in 1987. The chant varies with geography.
I was in the Hard Rock Cafe in Montreal. Everybody was speaking French, I couldn't understand a word anybody was saying. Then, Billy Idol's version of Mony Mony was played by the DJ and within seconds the dance floor was packed. Billy sang "Here she comes down singing "Mony Mony" and the crowd sang the Canadian Mony Mony chant "Hey motherfucker, get laid, get fucked" in ENGLISH! Unbelievable.
