I'm a little stuck... Click here to teach me more about this clue!

'make the skin tingle' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'unusually bad cloth' is the wordplay.
'unusually' indicates an anagram.
'bad'+'cloth'='badcloth'
'badcloth' with letters rearranged gives 'COLD BATH'.

'may' acts as a link.
