This word fits my mood right now:
正月太り
(しょうがつぶとり)
“shōgatsubutori”
putting on weight over the New Year’s holidays
There are a whole bunch of these, using the 太り suffix:
酒太り
(さけぶとり)
“sakebutori”
beer belly
着太り
(きぶとり)
“kibutori”
clothes which make one look fat
幸せ太り
(しあわせぶとり)
“shiawasebutori”
putting on weight from living a good (married) life
Note:
幸せ
(しあわせ)
“shiawase”
happiness, good fortune
Bonus:
着やせ
(きやせ)
“kiyase”
looking slim in clothes
Er…just water and some fruit for me today, thank you!
