sanketyam parihasyam va
stobham helanam eva va
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
One who chants the holy name of the Lord is immediately freed from the reactions of unlimited sins, even if he chants indirectly [to indicate something else], jokingly, for musical entertainment, or even neglectfully. This is accepted by all the learned scholars of the scriptures.
