Girls who talk about pointless emotional bullshit...
Like you'll be hanging out with them, having a normal conversation, and then something somebody says reminds them of something that was funny sometime, and one goes, "ohmigod, that is *JUST* *LIKE* _____" where ___ is something that only girls find funny, and then they giggle for 20 minutes while the guys stand around and look uncomfortable. But we put up with it anyway because we want the poon. I, however, draw the line at pretending to think it's funny.
