(also brain-killer)

1) someone who make others confused especially by talking.

2) any drug that prevents you from thinking.

3) something that is hard to understand.
1) - i had some plans but i don't know what to do now.
- you shouldn't have talked to him. he's a brainkiller.

2) i remember nothing about the accident. are you sure this drug is a painkiller instead of a brainkiller?

3) all the calculation is a brainkiller for me.
