If I were to infer the meaning from GP's comment, I'd characterize 'artslop' as "works created with some particular artistic intent, in which the literal elements are neglected in favor of their metaphorical connections, especially when these connections are more relatable to artists than a general audience". The connotation being that it's slop intended for other artists and critics, who will think "how meaningful and relatable!" and love it in spite of the poor execution of the literal elements.
