Our group start to bait trap
I believe the answer is:
web
'trap' is the definition.
(web is a kind of trap)
'our group start to bait' is the wordplay.
'our group' becomes 'we'.
'start to' suggests taking the first letters.
The initial letter of 'bait' is 'b'.
'we'+'b'='WEB'
(Other definitions for web that I've seen before include "Network (maybe worldwide?)" , "Complicated plot" , "Spider's trap" , "Insect trap" , "Spider's snare" .)
