Irish, Scottish and British do it for me... French is sorta okay for chicks, but for men it's utter faggotry. Italian is annoying male or female... but not as annoying as Spanish. The Scandinavian accent is cute for chicks but the dudes just sound silly. German is just frightening for male and female alike. All of the other European countries sound like Boratspeak to me.
Australian is hotter than hell for chicks and there is no cooler accent for dudes.
An Indian accent can make a chick sorta sexy, and the dudes can turn it into great comedy... more of a laughing with them than at them thing... the Indian deeble dobble accent can be infectious in it's hilarity. It's all but impossible for a dude to sound tough or intimidating if he's speaking with an Indian accent, "You kick my dog, and now I spit on your haircut and kill you, my friend!" ... it just doesn't work.
I won't even mention the chinky Asian and the Durka! Durka! Jihad! Muzzie accents... just horrible... all of them.
And last(and least)... the Russian whore accent... fingernails on a fucking blackboard. "You gives me myoney, and I do the sexy dance." uuuungh... it cuts through me like the whine of a dental drill.
That said... I'd go flat out Chernobyl on the ass of the chick in that video.
