Quoting from wikipedia, this is the definition of asymptote.
In analytic geometry, an asymptote (/ˈæsɪmptoʊt/) of a curve is a line such that the distance between the curve and the line approaches zero as they tend to infinity
Consider the curve $ \frac{\sin x}{x} $. It's asymptote simply is $ x = 0 $, yet the asymptote does cross the curve infinitely many times.
I am not aware of a special name for this behavior.
