It ' s a thing in a lot of states and has been around for a long time . <| sep |> Hah nice one , when i saw that it reminded me of this <| sep |> There ' s a sale on right now . <| sep |> The key to seeing from those guys ' perspective , I think , is that they ' re equally suspicious that both men and women haven ' t really played a given thingbut they don ' t actually care if a guy hasn ' t played it , because they don ' t actually want to have a deep conversation about their shared interests with another guy . They ' ll say cool shirt , man as a halfhearted invitation to talk about the thing , with neither side expecting to get much out of it even if they do both love the thing . Because 1 . they don ' t need another male friend and 2 . they can already get plenty of genderless sharedinterest conversation on Internet forums and the like . They ' re fullup on the acquaintance rung of sharedinterest chat . But a female friend with shared interestsboy do they need that . Someone who they could maybe end up playing games with on an ongoing basis as a life partner ? They ' re desperate for that . So they want to very quicklyovereagerly , s o m e w h a t s ociallytonedeaflyevaluate whether there are any shared interests there . More socially suave guys still do that , they just do it very obliquely and extend the probing out over several conversations . Much like you ' d expect a girl of even average social intelligence to do when on a date , to search for shared interests or lack thereof with a guy .
