fivegot 

When you forget to do something multiple times most likely because you were lazy or unmotivated.

Mother: Did you clean your room?
Child: I was going to but I fivegot. I couldn't figure out how to beat this level.

Bill: Yeah...Peter, I thought I told you to have that TPS Report with the new cover sheets on my desk by 2:00.
Peter: Uh, yeah. I meant to do it but I fivegot. I'll get ya next time.
