Interficere
 

Zou iemand mij kunnen vertellen wat dit in het Nederlands betekend?

I'm sorry, I took your advice in the signature, so I'm far too busy outside playing hide & seek and fucking myself to answer this question. Try again in a different tone of voice.

I'm sorry you're such a weener http://forum.scholieren.com/rolleyes.gif

Je kunt ook wel nederlands praten hoor

Yes I can, but in some cases I prefer English, especially when I'm dealing with a person who writes English more fluently than Dutch.
Back to your question. The verb form, 'interficere', imperative mode passive voice, could mean, in the appropriate circumstances, 'get yourself killed'. As an infinitive it means 'to kill'.
Satisfied?
