CC Antya 20.63

ei-mata mahāprabhu bhāvāviṣṭa hañā
pralāpa karilā tat-tat śloka paḍiyā
Word for word: 
ei-mata — in this way; mahāprabhu — Śrī Caitanya Mahāprabhu; bhāva-āviṣṭa hañā — being overwhelmed by ecstatic love; pralāpa karilā — said crazy words; tat-tat — appropriate; śloka paḍiyā — by reciting verses.
Translation: 
Thus overwhelmed by ecstatic love, Śrī Caitanya Mahāprabhu spoke like a madman and recited suitable verses.
