A cut-up is a person who makes other people laugh by doing silly, amusing things — pulling faces, cracking jokes, putting on a little show — especially when they are not supposed to. Teachers know this person in class: the one who gets a giggle going while everyone should be listening.

A cut-up is是 by doing silly, amusing things靠做傻氣、好笑的事 who makes other people laugh逗大家笑的 a person人——pulling faces扮鬼臉、cracking jokes講笑話、putting on a little show來一段小表演——especially尤其是 when they are not supposed to在不該鬧的時候。Teachers老師 in class在課堂上 know this person都認得這種人：while everyone should be listening在大家都該專心聽的時候，the one who gets a giggle going把笑聲弄起來的那一個。

The word is informal, a little old-fashioned in some places, more American than British, and it often carries a sigh: funny, yes, but not at the right time. You would not usually call a professional comedian on stage a cut-up; the point is they are being funny where it is a bit naughty or out of place.

The word is informal這個字口語，in some places在某些地方 a little old-fashioned有點過時，more American than British美式多於英式，and it often carries a sigh而且常帶著一聲嘆息：funny, yes好笑是好笑，but not at the right time但時機不對。You would not usually call你通常不會把 a professional comedian on stage台上的職業喜劇演員 a cut-up叫作 cut-up；the point is重點是 they are being funny他們是在搞笑，where it is a bit naughty or out of place而且是在有點調皮、不合場合的地方。

Though actually, the verb cut up has other lives — to chop food into pieces, or to be very upset (she was cut up about it) — so this noun is only the clown, not the salad and not the sad feeling.

Though actually不過其實，the verb cut up動詞的 cut up has other lives還有別的身分——to chop food into pieces把食物切成小塊，or to be very upset或非常難過（she was cut up about it她為那件事很難過）——so this noun所以這個名詞 is only the clown只是那個活寶，not the salad不是沙拉，and not the sad feeling也不是難過的心情。
