The 7 TRAITORS,
The 7 FROM HELL?,
The 7 SATANS? - LOL.
Playing off of what someone else posted I suggest:
The 7 DWARF RINOS
The perfect name will come up all of the sudden, and we'll know it will be the perfect one! - This "term" will be important, because we'll refer to these ,7 WEASELS, for years to come :)
