Let a [[HelloNurse hot, sexy woman]] stroll through a crowd of males and one or more of them will emit this classic sound, guaranteed. (It's most accurately transcribed as "Wheet-WHOO!", although a simple "Whoooo!" might also suffice.) The Wolf Whistle is a staple of old films and cartoons of the '30s and '40s, most notably the works of Creator/TexAvery. The Wolf would acknowledge the presence of Red with this whistle.

The Wolf Whistle isn't limited to men expressing their appreciation of women. It can also be used to express admiration for anything desirable. A hot sports car, awesome home electronics, a new jet fighter can also elicit this response.

It should be noted that the Wolf Whistle isn't restricted to men. On occasion women will use it to express approval of the new stud in the environment.

This was noted the most common Wolf Whistle, usually approval of thought to find a person sexily attractive. A slightly different version of the Wolf Whistle involves a single, lower-pitched elongated tone, usually while the character stares at the person/object in question. It more commonly used today than the classic whistle.

Variations include the "wolf howl", the "purr", the "growl", and the "dog pant". Note that carnivorous mammals always seem to be referenced.

May also have the whistler become [[MetaphoricMetamorphosis an actual wolf, or have a wolf head]]. See also ConstructionCatcalls.
