'they're drunk' is the definition.
The definition suggests an adverb but the answer is not.

'the heart of texas' is the wordplay.
'the' becomes 'definite article' ('the' is the definite article in English).
'heart of' indicates the central letters.
'texas' becomes 's' (I can't explain this - if you can you should believe this answer much more).
The middle letters of 'definitearticle' are 'tea'.
'tea'+'s'='TEAS'

'around' is the link.

Can you help me to learn more?
