Hey Sexy Mama! （ちゃん ね）

He Says:
chan ne　（ちゃん　ね） = pretty girl.
Usually nechan is girl. It's a normal word. But if the word "nechan" gets reverse,it turns to have a little bit sexy. So jp men sometimes say chan ne~ to sexy girls or hookers instead of simply nechan. But we don't say chan ni~ to boys(nichan is boys or brother).

She Says:
Something you might hear walking down the street, the way that guys in English might call "Hey sexy mama" or whatever. If you're a foreign girl in Japan, guys might be more apt to say this loudly in front of you, thinking that you won't understand. So remember it and scare the shit out of them when you comment back. Really. It's fun.

The next word is...ぺちゃぱい。
