Used to describe someone really swaggy or cool. They tend to be really confident, and deserves everyone’s attention.
“Yo! That dudes got some serious buck lench!” “Man, you’ve got some cool buck lencher moves!”
An exaggerated swagger that is worthy of note. A person walking in a way that is clearly trying to be as cool / swag / drip as possible. If someone has a buck lench they appear to be putting some effort into looking as cool as possible.
"Check out this dudes 'lench."
"DAMN I'm loving that guys buck 'lench."
"Yo your buck 'lench is craazy brah"
