An combination of the words "what" and "had." The combination is mostly used in spoken conversation, but can be accepted in text form.
"When I told him what'd happened, he looked at me like I was crazy."

While neither an officially abbreviated word nor a recognizable transitional verb, the word is an valid auto-generated substitution within the iPhone's keypad. It is generally followed by the phrase 'it do?' as an inquiry regarding one's status however by itself it is not easily understood.
"What'd? What'd my iPhone think I was trying to type? That ain't proper grammer."
