bestest
Beyond best, grammatically
Bestest is a playful superlative of best, formed as if best weren't already superlative enough.
Used mainly by children or adults speaking affectionately: You're my bestest friend.
The redundancy is the point—it signals warmth or childlike enthusiasm rather than grammatical confusion.
