Congress leader Shashi Tharoor on Friday called political defectors in India "snollygosters' role model" and shared a video of a chameleon changing its colours as it climbs a multi-coloured stick. "The changing colours of political defectors...[is] brilliantly illustrated by this...chameleon!" he tweeted. As per Merriam-Webster dictionary, 'snollygoster' means a shrewd or unprincipled person.
