Ill-conceived; not well thought out or planned. Likened to something that has only cooked in the oven for half the time necessary. Stop coming up with these half-baked schemes! They'll never work!I could tell the project was only half-baked from the beginning, but I kept my head down and said nothing.
half-baked
1. mod. badly thought out. It would have been approved if it weren’t so half-baked.
2. mod. alcohol intoxicated. Fred got himself sort of half-baked every Saturday night.
