In Kiwi (New Zealand) slang we often add "as" to adjectives, like "sweet as" or "good as" to mean "no problem!" or similar ... without something after the "as" to compare it to (kind of like "good as gold" but without the word "gold"). Anyway, my Kiwi friend (a guy) studied in the U.S. for a while, and once he held open the door for a girl, and she said, "Thanks!" He called after her in chirpy Kiwi slang, "sweet as!" She heard, "Sweet ass!" and was not impressed! After a moment he realized what she'd heard and tried to explain, I'm not sure whether she believed him or not. :-)
