Muchas besos - is it flirty?

Muchas besos - is it flirty?
 

Hello to everybody.

I am a beginner in Spanish and whant to know how flirty/intimate the phrase "muchas besos" as a goodbye is. If a guy sent it to a girl, does it mean something more than just bye?

Thanks

It must be "muchos besos."

Just like sending "many kisses", depending on the context and the persons, it can or not be flirty.
