SB 10.9.6
sañjata-kopah sphuritarunadharam
sandasya dadbhir dadhi-mantha-bhajanam
bhittva mrsasrur drsad-asmana raho
jaghasa haiyangavam antaram gatah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Being very angry and biting His reddish lips with His teeth, Krsna, with false tears in His eyes, broke the container of yogurt with a piece of stone. Then He entered a room and began to eat the freshly churned butter in a solitary place.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
It is natural that when a child becomes angry he can begin crying with false tears in his eyes. So Krsna did this, and biting His reddish lips with His teeth, He broke the pot with a stone, entered a room and began to eat the freshly churned butter.
