请教英语高手们 I don't think you're ready for this jelly.的意思是? 谢谢~~
谢谢，这句话出现的语境是You are in a gym. You’re waiting to use the treadmill, but the woman on has obviously gone about 30 minutes a time of much deal.( What will you do? )
--Hop on the treadmill and run with her, saying, “I don’t think you’re ready for this jelly.”
请问这里的jelly如何理解呢？
