in Brazil there's an idiom: " Abraço de Tamanduá "

The idiom “anteater hug” is used to refer to the embrace or greeting of a false person, that is, who wishes evil to the person who greeted them.

This expression arose from the observation of a tactic of attack and defense of the giant anteater, a species of mammal quite common in the Brazilian cerrado region.

The anteater is naturally a disheveled animal, with very little sight and hearing, however, when it feels threatened, it uses its enormous claws to defend itself.

The animal stands up on its hind legs and opens its arms showing its claws, as if to give a "hug". In reality, this is a “deadly hug”, as the anteater's claws are very strong, even capable of killing a jaguar.

From this position, the expression “hug of anteater” began to be used to define the hug that someone receives from a person who does not sympathize or is false.

For example, when two people are in the same environment, but one of them hates the other and will still greet and hug her, it is said that she gave him an “anteater hug”.
