The act of mispronouncing, blending or blundering of two or more words, with an amusing outcome, which tends to occur under high sleep deprivation that mimics intoxication. The word spleech was derived from the very action itself.
Sebastian is no stranger to spleeching; when he wanted to borrow his friend's phone, he asked, "can I use your phlone (pronounced 'flown')?"
