Jackass of all trades 砸锅专业户

Jackass of all trades describes someone who is exceptionally bad at everything. It is very hard to work with this kind of person because they are likely to screw up everything in process but would never admit that it's their problem.

Jackass of all trades指任何事情都做不好的人。跟这一类人一起工作很难，因为他们可能会把进展中的所有事情都搞砸，而且还不肯承认是自己造成的。我们可以戏虐地称为“砸锅专业户”。

Jackass这个词在英语里多半都是用来骂别人“傻、蠢、笨”的，所以，生活中还是尽量少用吧。
