get one’s rocks off
- verb to obtain sexual satisfaction, achieve orgasm, ejaculate. An American vulgarism which became part of the hippy linguistic repertoire; some British users of the expression are unaware that rocks is a direct euphemism for testicles. (In American usage nuts or other terms could be substituted for rocks.) In the later 1970s the phrase was extended to mean to indulge oneself or enjoy oneself generally rather than in a specifically sexual sense. It now sounds dated.
