neffing

Neffing is posting on a forum about basically nothing in order to drive up post totals.

An example is replying with only a smiley or one word such as "lol": this causes a lot of useless post. Rules often include - no neffing or you'll have your post count or rank significantly reduced!

Neffin' Out

To leave work everyday at the same time regardless of when your supervisor says your shift is supposed to end.

Nick has been neffin' out at 2:30 everyday because he fucking doesn't work late and he fucking doesn't work overtime.

Netfinger 

Finger banging your girl’s wet pussy so much during hours of watching Netflix that she prunes up the skin on your finger(s).

Our night of Netflix and chill resulted in a bad case of netfinger.
