Here's what might be happening:
* Typo: It could be a misspelling of "despicable," which means "worthy of contempt or disgust."
* Made-up word: Someone might have invented the word to express a specific feeling or concept.
* Slang: It's possible the word is used in a very specific context or community as slang.
Without more context, it's impossible to know what "dispickable" means.
