Two quick questions
 

1. What does - Out of memory, too many mymalooks - or something like that mean?
2. Horror mark, can someone further explain this spell to the detail, precisely the chances of attacks ect.

"mymallocs" perhaps? Those of us who write C code often end up wrapping the standard "malloc" routine or writing our own, depending on our needs. Probably this is JK's custom version of malloc. malloc is used for memory allocation of data arrays and objects. (It probably stands for "memory allocator".)
Having too many mallocs means you're out of memory. ;)

2. The first part is easy. The spell targets the largest creature on the battlefield and assigns a "horror mark" level. Every additional casting increases the horror mark level by 1. That being said, the horror mark level is unknown during play. Furthermore, I know of no one who can tell you odds of getting attacked by horrors any given turn or which horror based on horror mark level. I will say it seems to take more than one guy spamming it throughout the battle to be effective.
