ladies finger
When a guy's fingers smell like a stinky sock after he's been sniffing up a woman's snatch.
'He came out of the bathroom and his fingers smelled like a dead rat. He must've been sniffing up a lady's snatch.'
'I saw his fingers and I knew he was sniffing up someone's snatch. He's a finger sniffer.'
'He's got lady finger vibes. I can smell it from here.'
