'sickened' is the definition.
('disgust' can be a synonym of 'sicken')

'sid turns up with two other men' is the wordplay.
'turns up' is a reversal indicator.
'with two other men' becomes 'gusted' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'sid' written backwards gives 'dis'.
'dis'+'gusted'='DISGUSTED'

'that' is the link.
