Floppy..?

Was feeling a bit..u know..'xian' over the past couple of days..no particular reason, just a dip in energy levels and happiness index generally..

So I did what i always do..sent out a whining watsapp(yes, i'm totally appreciative of this app) 'feeling lethargic..dont feel like doing anything lately'..

22 hours and 3 irrelevant msges later(such as, 'the hospital is really messed up..haven't received my pay'), the somewhat-sympathetic response came - 'i have been like this all the time..u will have a day full of energy and the rest of the week feeling floppy'

Floppy..??

How amusing to hear this word as an adjective for describing a mental state/mood..and how amazing that it seemed like the perfect ang moh counterpart of 'nuah'..
