Penis — euphemism obtained by modifying the initial letter of хуй. Used in online games, comments, or casual chat to express annoyance without getting banned (да пошёл ты на фуй — “oh, go fudge yourself”).
Устарел язык Эзопа,
Стал прозрачен как струя,
Отовсюду светит зопа,
И не скроешь ни фуя.
Aesop’s language is outdated,
Clear as a streaming light,
From everywhere shines the backside,
And nothing stays out of sight.
(И. Губерман)
