At work we develop for embedded systems. Using the heap can raise unknown effects sometimes. So we always try to avoid using it. To show our attitude regarding the heap we want to make T-Shirts like the No Ma'am shirts from Married... with Children but with No Heap instead of No Ma'am. Now we need a meaning of the acronym. Our currently idea is:

Nerdy
Opponents of
HEAP
E
Allocation
Practice

We do not find a good word for the E, we also aren't native speaker, thus we are not sure which synonym for word like based can be used in such context. So i want to ask if someone has a good idea or even a better idea for the whole acronym :)
