A song by Guns N' Roses on their debut album, Appetite for Destruction. Essentially, it's about one's initial introduction to the seedy underworld of America.

It also serves as a nice pump-you-up song.
Welcome to the jungle, we got fun and games.
We got everything you want, honey we know the names,
We are the people that can find, whatever you may need.
If you got the money,honey, we got your disease in the jungle
Welcome to the Jungle...

Once a Guns N' Roses song, this term may now refer to the monstrosity known as an unshaved/untrimmed pubic area. Few who enter the confines of such a beastly jungle ever return to tell about it.
"I'm playing Amy's song, Welcome to the Jungle."

when some asks you "were you welcomed to the jungle?" they are really asking you if when you fingered a girl, was there pubic hair or not. and if so, how much.

An invitation to groom or admire one's pubic hair. Originally from a Guns 'N Roses song, however, Mountain Pointe High School turned the phrase into a travesty. It is now the butt of all jokes among students in the yearbook class. Not really. It actually has everything to do with anal sex, ever.
Welcome to the jungle, Mountain Pointe High School! Please proceed to admire my pubic hair and/or have anal sex with me.
