Nice.
Sandbagger is a term I've only heard here. To describe someone who's not telling the whole story but not because they're embellishing, instead the opposite, they're being overly discreet.
Say someone is worth $10 million. If said someone will only admit to $1 million, they're sandbagging.
Alright, now it makes sense.
What's a teabagger then? 😄
