After Mat broke up with my friend, he would act extremely shady all the time, pretending to lose his phone, and pretending not to receive SMS's. At times there was even no toilet paper, or shit on the walls. He is a fairweather friend.
A person who only hangs out with you (basically uses you) when good things go on, but neverhang out when there's not so good things.
Michael is such a fairweather friend because he only hangs out with Justin at parties and other fun things, but whenever he needs something Michael just bails on him. What an ass!
Someone who is always there when the sky is blue (and when they need something from you), but never there when the sky is gray.
Guy/girl- Can't you see I am your friend?
Other guy/girl- Yesterday wasn't such a nice or positive day, and where were you then? Trying to look tough in some stupid fuckin youtube video about your trip to the ruins out in no man's (no human's) land?
Guy/girl- That was my treat to me!
Other guy/girl- You've always been a fake friend, pretending to be somebody's friend when you're not. Pretending to be something you're not. You're a fairweather friend, a fairweather motherfucker.
