A ying ling is another word for a beer.
"she didn't talk to charlie
our old bass player
and she didn't go off with steve
not the cougar, not the cougar
she took me up to the balcony
past kenneth keith kallenbauch
and give a ying ling to me."- New Jersey Girl, Nerf Herder Lyrics
A mispelling of Yuengling, a specific brand of beer.
Where you get that crazy ying ling?
It's Yuengling, doofus. Learn to spell.
