よもすがら

Meaning: 一晩中 (all night)

First, kanji.
why is it all night? I know if you can read chinese characters, it's easy to know the meaning. But think of it as「夜」は「終わる」まで if you can't read chinese.

Second, meaning.
「夜も」+「すがら」 which means from start to end without break = all night.

終夜、カラオケ。

終夜、麻雀。

終夜、友と語り合う。

You certainly need lots of energy and youth to do all that! HAHA.
