"Thar-She-Shid" is an urban word used to describe a certain point of Intoxication, it's beyond "Buzzing" and borderline "Blacked out". the word is derived from a "Typo" when one is trying to use the common adjective "Thrashed" but the brain and thumbs are no longer having a healthy correspondence.
"HeY MoM I CaN't MaKe it To PicK uP mY KidS tOnight, Im totAlly TharSheShid.. I'll Pick Them Up In The Morning"
