Reading the other comments, I think that's right about her being cold - I think he does say 'cold' - yet crying out for ice water. Mek is 'make' - what you do is what makes it happen. "you do it to yourself" is still the best way I can think of to translate 'a it mek' (in Lancashire dialect that might he she makes it happen) (but with a = uh = her).

I heard this played by Cerys Matthews on BBC Radio 6 and can't stop listeneing to it - LOVE IT. To me it says "You do it to yourself" followed by "fool me once, shame on you, fool me twice, shame on me". I think these things (falling over, having a hangover) are being done to draw attention to herself, and he is the sweet nanny goat rubbing her belly good : )
