Something blatant is very obvious and offensive. Don't get caught in a blatant lie, because you won't be able to weasel your way out of it.

Blatant acts are done without trying to hide them. This adjective is probably from Latin blaterare "to chatter, croak" or Latin blatīre "to chatter, gossip." A near synonym is flagrant.
