A term used in the form of "emotionally" connecting with
somebody new.
Derived from the construction toy/puzzle known as "k'nex" where in which pieces of
plastic are connected together to make buildings,
cars etc...
For example,
Two guys are in a
bar, one
guy goes over to a girl and they talk for half an hour, gaining her phone number. The other
guy then nudges him and says
"You totally just knexed her man!"
