thalweg 

A lazy person who hides from teammates to avoid work while still progressing towards the desired outcome.

Someone who sits in the slipstream of high-performers to get where they want to go while minimising the effort they exert themself.

The lowest path along a riverbed.

“How did Kevin get a HD?! That thalweg did jackshit all semester!”
“True, that gray man did fuck all.”
