gaudimonium

From gaudium (“joy, delight”) +‎ -mōnium (“collective or obligation”, perhaps used intensively).

gaudimōnium n (genitive gaudimōniī or gaudimōnī); second declension

1. joy
   • c. 27 CE – 66 CE, Petronius, Satyricon 61:

     Niceros delectatus affabilitate amici: "Omne me, inquit, lucrum transeat, nisi iam dudum gaudimonio dissilio, quod te talem video. Itaque hilaria mera sint, etsi timeo istos scolasticos ne me rideant. Viderint: narrabo tamen, quid enim mihi aufert, qui ridet? satius est rideri quam derideri."

     Niceros was delighted by his friend's amiability and said, “May I never turn another penny if I am not ready to burst with joy at seeing you in such a good humour. Well, it shall be pure fun then, though I am afraid your clever friends will laugh at me. Still, let them; I will tell my story; what harm does a man's laugh do me? Being laughed at is more satisfactory than being sneered at.”

Second-declension noun (neuter).
