Tip to one side
I believe the answer is:
tilt
'tip to one side' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for tilt that I've seen before include "Lean sideways" , "Slope; use a lance in jousting" , "Slight inclination" , "Slant - joust" , "Incline, slant" .)
