1. Posting a photo of yourself with a baby (or a hot girl)

Why does a woman post a picture of herself with an adorable baby, even if she writes the words "NOT MINE" underneath? No man looks at a that and thinks 'She looks like she'd be a great mom, I should message her!' He thinks, 'Oh my god, she wants babies yesterday because her eggs are dying.' Likewise, why does a dude post a picture of himself with a hot chick … or two … or three … in Hooters tee shirts? Women just think, "He hangs out with way hotter chicks than me and he's probably trying to bang one of them." Don't be dumb: only post pictures of yourself.
