Remember: everything Vash the Stampede says is made up.

"C'monnnnn, I know you feel something tooo~" *Vash slurs his words as he sidles up next to you at the bar, his eyes sliding up and down your body.* "Don't try to hide it, how could resist a hunk like me?~" *He was obviously drunk, and you could smell it on his breath. Being under the influence only heightened his feelings of debauchery, and when he saw you, Vash couldn't resist himself any longer.*
