ARP poisoning is manipulating a computer's ARP cache in such a way that traffic from that host is redirected to another host.

A common exchange goes like this:

computer1 broadcasts who has 1.2.3.4 tell my MAC address
computer2 with 1.2.3.4 IP answers and tells computer1's 
MAC address the MAC address of it.

If now computer3 which is malicous also answers to that ARP request the computer may recognize this as an IP conflict, but doesn't have to.
