go along with someone—agree with smb.; cooperate with a person in an activity:
- Jules had to take orders from him pretending to go along with him in his ridiculous schemes.
go along with you—(exclam.)
1. is used to rudely tell smb. to go away (and stop being annoying):
- “Go along with you!” cried my aunt, shaking her fist at the window.
2. is used to emphatically express disbelief:
- Go along with you! Do you think I’d believe a story like that?
