「發水樓」

(pos:名詞)
<explanation>
yue:指賣樓嗰陣，宣稱嘅呎數大過實際可用呎數嘅單位（量詞：層）
eng:literally, inflated flat; flats that have a useable space much smaller than the claimed size
<eg>
yue:呢層發水樓，話就話五百呎，實質度出嚟得三百五，真係離晒譜！ (ni1 cang4 faat3 seoi2 lau2, waa6 zau6 waa6  ng5 baak3 cek3, sat6 zat1 dok6 ceot1 lai4 dak1 saam1 baak3 ng5, zan1 hai6 lei4 saai3 pou2!)
eng:This inflated flat claims to be 500 square feet, but actual measurement gives only 350. This is outrageous!
