Bob regularly rejected team on left (5)
I believe the answer is:
float
'bob' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for float that I've seen before include "Carnival display" , "Bob" , "Put forward (an idea)" , "Lie on the surface of liquid." , "Levitate" .)
