She melted his butter with her warm smile.

Her sense of humor really butters my biscuit.

Her cooking skills are so amazing that they always melt someone's butter.

Her cooking always melts someone's butter.

She was buttering his biscuit with compliments.

She really buttered his biscuit with that compliment.

Butter will not melt in someone's mouth.

He cut through the crowd like a knife through butter.

He puts butter on his bread every morning.
