'cliquey crowd' is the definition.
'in-group' can be an answer for 'crowd' (thesaurus). I am not certain of the 'cliquey' bit.

'pouring out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'pouring' anagrammed gives 'IN-GROUP'.

Can you help me to learn more?

(Other definitions for in group that I've seen before include "clique" , "Coterie" , "ruling party" .)
