Masculine name. French form of Gislenus, a Latinized form of the Germanic name Gislin, derived from the element gisil meaning "hostage" or "pledge". Popularised by 7th-century Belgian St Ghislain of Belgium, who even has a town there named after him.

This name is used synonymously with the term "pleasantly awkwardly random", as this is typically the personality of most named Ghislain.
She seemed crazy when we were first introduced, but although she would spout out nonsense, she was such a Ghislain.
