Ramayana
शूर्पणख्याश्च भर्तारमसिना प्राच्छिनत्तदा । श्यालं च बलवन्तं च विद्युज्जिह्वं बलोत्कटम् । जिह्वया संलिहन्तं च राक्षसं समरे तथा ॥ 7-23-18 ॥
he then cut down with his sword the husband of Shurpanakha — his brother-in-law, the strong and mightily powerful Vidyujjihva, the Rakshasa who was licking with his tongue there in the battle.
