So, if you 'murder out' your smart, can you have a 'murder of smarts'? Or, how about, a 'conference of smarts'? From M-W.com, " a representative assembly or administrative organization of a religious denomination." Seems like smart owners are a fairly fanatical group...
Ok, don't like those, how about a few of these? Personally, 'army of ants' conjures up a group of smarts, so how about an 'army of smarts'? They'll visit if you have food! Or, maybe, a 'party of smarts', like 'party of jays' at link below? Again, they'll come if you've got food!
