A lench is a male or female that takes you to the very edge during sexual activity, and then promptly terminates the act, leaving you blue balled in a pitiful state.
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"
A comps leech is someone who goes on a Vegas trip that is paid for mostly by comps from the rest of the group without actually providing any comps. This parasite tends to be a redder, which explains their inability to accumulate any substantial comps. Despite receiving a free room, they refuse to pay for even a $7 cab ride. They show no appreciation for the free stuff they are receiving, and often feel entitled to even more stuff.
Mich: How come I have to sleep on the cot???
Chi Chi: Because my back hurts, and because you are a comps leech.
