'it guys?' is the definition.
The definition suggests a singular noun which matches the answer.

'style say kept up around latest of crack' is the wordplay.
'style' becomes 'mode' (synonyms).
'say' becomes 'eg' (both can mean for example).
'kept up' is a reversal indicator (in a down clue, letters go up).
'around' means one lot of letters goes inside another.
'latest of crack' becomes 'k' (I can't explain this - if you can you should believe this answer much more).
'mode'+'eg'='modeeg'
'modeeg' in reverse letter order is 'geedom'.
'geedom' placed around 'k' is 'GEEKDOM'.
