Scab

a replacement friend;
not really a friend;
someonee you use after another friend leaves you...

Random dude: "Wow, You moved on from being friends with Shaquasiaa to being friends with her already? She just left, I thought yall were besties...

Girl: "Nah she's just a scab, I`ll dump her when Shaquasiaa gets back..."
