viper
Triangular-headed serpent
A viper is a venomous snake, typically with a thick body and hinged fangs that fold against the roof of the mouth.
The term covers many species across several continents.
Figuratively, a viper is a treacherous or spiteful person: She turned out to be a viper who betrayed everyone who trusted her.
To nurse a viper in one's bosom is to shelter someone who will ultimately harm you.
