Meaning of んな after verb in て form


> 関口やナベちゃんに「そんなとこ、ボッと立っ **てんな** よ」と言われたことを思いだし、情けなさそうにうなずいた。  
>  He recalled being told by 関口やナベ that ??? and bowed his head miserably.

To be honest, I'm stuck on everything in the quotes (something about
blushing?) but, in particular I'm puzzled about the んな part in bold after the
te-form verb. I'm guessing it's a contraction of たってのな but I've never seen
that before either.




It's a contraction of ～ているな. The な here means 'don't', as a negative
imperative. 「ボッと立ってんなよ」 means 「ボッと立っているなよ」 'Don't just stand there dazed.'
