According to the Urban Dictionary a ‘Hot Mess’ is defined as, ‘When one’s thoughts or appearance are in a state of disarray but they maintain an undeniable attractiveness or beauty’.
I like to think I’m a Hot Mess, but my hotness is more due to hormonal flushes than ‘maintenance of my undeniable beauty whilst in a state of disarray’. The ‘Mess’ part is due to my lack of ability to make my appearance a priority.
