unfortunately i have slits in my eyebrows.. but... it ACTUALLY came from accidents!!!
What makes it even more ironic.. is that i have one on the other eyebrow in the EXACT same place.. symmetrical !! .. ALSO ACCIDENTAL!!
one was from rope burn, and the other was a combination of smashed glass and a hockey stick lol...
either way.. mine look natural (because its not shaved or waxed) and is permanent.. but ppl still think i did it intentionally to "look cool"
personally tho i dont mind it and i dont think its un-attractive (actually sometimes i get complimented for it!) - but only because its natural

I was blessed

haha
either way i agree with most of you... It isnt haram per say - but if your doing it for a girl.. theeeeennn maybe u need to think about it deeply..
hamdulilah ur not going to do it... but just keep in mind its all about the intention!!
wasalam
