An Ask.fm War is when a person goes on anonymous; people who often do this are called 'anon'. And anon starts shit on a person's account causing a fight between anon and the person with the ask account. In some cases it can get so bad that people that are friends with the person being attacked on ask can take their side and argue with anon, causing an All-out war.
Anon: Ur a pussy bitch and you fucked your dog
Random Person With Ask Account: Um no I didn't actually, stop trying to start an ask.fm war with me.
