n. A large arboreal boa of tropical South America . Anacondas hold the record for heaviest, if the not longest, snakes in the world. Anacondas are constrictors. The
snake squeezes tighter each time its prey breathes out, so the prey cannot breath in again. This goes on until the prey dies of suffocation.
Also can be used as a euphemism for a certain male
bit, but this is discouraged as it tends to give the slightly nerdier
among us odd mental images of being squeezed to death and devoured by a penis. For most of us, this is not exactly erotic.
