Said by Patrick in the Spongebob episode "Hall monitor" Wee woo expresses great emotion, in Patrick's case it is fear. It is also the sound that police officers make when they do not have sirens. Or like Patrick are scared and say it to remind themselves that they are tough police officers :D

A person who gets the vaccine and and flaunts it will high end shopping, trips, and parties

Wee woo is the sound a siren makes. It is used in jest, to make fun of police cars, fire engines, ambulances, anything with a siren, really. Popularized by short films.

The sound that sirens make.

Weewoo can be used when expressing how you feel whilst drunk. Weewoo means oh yes I’m so sexy everyone loves me.

The word weewoo means a stupid or a dumb person.

An ambulance,
or an emergency.
