There is a new dating trend starting this year called Prowling according to Metro News.
What is "prowling"?! Glad you asked! Well first you gotta know what a "prowler" is! A "prowler" is "a person who’s hot and cold when it comes to showing romantic interest."
A true Katy Perry song "Cause you're hot then you're cold. You're yes, then you're no. You're in then you're out." and so forth.
So now you know what a prowler is so prowling is based on that - it is about playing with someone's emotions which just sounds cruel and like a rollercoaster ride. Well here is the start of 2019 in a nutshell -- first Kylie Jenner gets dethroned on Instagram by an egg and now prowling... oy!
