Nếu bạn "twist someone's arm", nghĩa là bạn thuyết phục ai làm một việc gì đó.

Ví dụ:

• I know you said you didn't want to go out tonight, but can I twist your arm? I could really do with a night out.
• I shouldn't have one of those cakes as I'm on a diet... But go on, you've twisted my arm!

Lưu ý: "to pull somebody's leg" có nghĩa là lừa ai, trêu ai.
