Friend Up 

F U.. or Friend Up means to step up as a friend and do something a friend requests; or to hangout. It can also mean to become friends with someone. Like the term 'man up', it's almost the same, but.. friend up means 'be a friend'. Friend Up is changing the way people see the abbreviation F U.

Person 1: Dude come inside the beer store with me

Person 1: Come on man... Friend Up
Example 2:
Person 1: Hey do you want to Friend Up?
Person2: Ya lets do it

Friend-Up 

A friend-up is where you have a friend. And they are clingy and you don't really want to be friends with them. But if you 'reject' them,they take it to heart,cry and spread rumors. So you have to handle them with care.

Girl 1; Uggh. This girl is annoying. She calls me every second of the day...I don't want to be friends with her..But I don't know how to tell her..

Girl 2; OMG. I know. That's annoying. Just 'Friend-Up' with her.

Fucked up friend boy 

This word orginated from fuck boy" and has been expanded upon. Where a friend has the same intention as a "fuck boy" but only as a friend. Where you ask said friend "hey Tim would you like to go fishing and his response is Ya sure then blows you off later and then gives you a lame excuse that he has to help his dad do his taxes. Like come on a retarded kid doing taxes for a very intelligent man. Here are signs that your friend is a "fucked up friend boy". He makes plans, you show up and follow through then he blows you off. Then Timmay plays it as "o" well I meant to come but this girl texted me and I had to drive like 120 miles in my new car and still did not get laid even after sleeping in the same bed and proceeds to say we should hang out this next weekend. Just enough conversation and interaction to lead you on that your still friends.

Hey Jimmay you want to hang out such but I won't show up like the last time oh OK cool. Fucked up friend boy
