Hrímgrímnir

Hrímgrímnir (Old Norse:, 'frost-masked') is a jötunn in Norse mythology. He is invoked by Freyr's servant Skírnir as he tries to coerce the beautiful jötunn Gerðr on his master's behalf.

Name
The Old Norse name Hrímgrímnir has been translated as 'frost-masked'.

Attestations
In Skírnismál (The Lay of Skírnir), after Gerðr refuses to marry Freyr, his messenger Skírnir threatens her with a curse involving her marriage to Hrímgrímnir in Hel: [Skírnir:] Hrímgrímnir is the name of the giant who shall possess you [Gerðr], Down below Nágrind [the gate to Hel’s realm]. There let wretches on the roots of the tree Give you goat piss. A better drink you will never get, Maiden, from your mouth, Maiden, to your mouth.

Theories
Scholar John Lindow comments that Hrímgrímnir is evidently a "part of something bigger"; if Gerðr refuses Skírnir's offer, she will "be denied all ordinary sexual congress", resulting in social consequences—even though she would be married, she would live in social exile.
