To shag, to screw. Derived from юлдач — the shagger becomes his own verb, which has a certain logic to it. Circulates mainly in very informal registers: forums, online diaries, texts you don’t send your mother.
Юля рыдает из-за Серёжи, дебильного идиота, который целку Иру юлдачил.
Yulia is weeping because of Seryoga, that stupid idiot that screwed the virgin Ira.
