from a viewpoint of physics, each interaction releasing energy is to be considered kind of a "bond" inbetween particles
in chemistry however, we only tend to call something a "bond" that fixes the geometric relation atom(group)-atom(group) , and "stays" there.
... which VDW interactions don't do: they're permanently broken and reestablished elsewhere
so, if I was in your shoes, I'd mention those effects, but would call them "weak interactions" and point out, that they're in the ballpark of 50 - 100 times weaker than 'normal' bonds.
