snápr (ON) noun

Commonly refers to a ‘dolt’, ‘fool’ or ‘charlatan’ and listed among the heiti synonymous with ‘unwise man’ in the Poetic Edda; cognate with ModE ‘snob’. The term is also used to describe the tip of a gimlet or similar pointed object and can allude to male genitalia. In Medieval Icelandic law snápr refers specifically to someone who makes false boasts of having lain with a woman (Jó Mah 30). The penalty for this type of boast was the same as having actually committed the offense. Snápr also appears in a marginal gloss for maðr at verri (‘a worse man’) and elsewhere in MLL.
