Definition: In the context of computer programming and related fields, "preggers" refers to a situation where a program or algorithm is used to execute multiple times before it reaches its maximum execution time. This can happen when the program has been compiled with too many optimizations (such as using SIMD instructions for parallel processing) that consume more memory than necessary. The term was first coined in the 1970s by computer scientist John McCarthy, who referred to this phenomenon as "the curse of preemption"
