吸煙有害健康，而一些吸煙者只在社交場合吸上幾支，他們不會上癮，也不是為了緩解緊張情緒，這就是“社交吸煙者”。

Chipper refers to a person who smokes cigarettes only occasionally; a social smoker.
“社交吸煙者”指的是偶爾吸煙的人，一般是在社交場合。

Chippers are able to smoke just a few cigarettes regularly but never become pack-a-day smokers.
“社交吸煙者”能夠做到定期吸幾支煙，而從不會變成大煙槍。

Rather than smoking because they feel pressured or tense, chippers usually smoke because they are happy or are enjoying themselves, for instance at a party.
“社交吸煙者”吸煙不是因為感到壓力大或者緊張，通常他們吸煙是因為很高興或者很享受，比如在派對上。
