A close round, with the top 3 positions in the balance right to the end. Tony Abell scored 5, with a 3-way tie for runner-up: John Barrs, Alan Mallach and Dan Widdis. The real definition was #2:
Scottish colloquial. A person with a large round face; (also) a stupid person. Frequently as a term of mild abuse. [ < baw, representing a Scottish colloquial pronunciation of ball + heid, variant of head].
5 players voted for it, and John Barrs came up with the same etymology supporting a rather different definition.
For anyone wondering why I chose not to combine #2 and #4: It is true that the two offerings share an etymology, and a regional label (“Scottish”); but neither etymologies nor labels are, strictly speaking, part of the definition. Leave these nondefinition elements out of account, and consider only the definitions, and the two are quite different; and the rules talk about combining definitions that are close to one another. It is true that Roundhead was unflattering (and, for that matter, so was Cavalier) but there is a difference between a descriptive rude name for a member of an opposing political faction, and a largely content-free term of abuse.
1. Phon. A transitional sound in speech which is produced by the changing of the mouth organs from one definite position to another, and with gradual change in the most frequent cases; as in passing from the beginning to the end of a regular diphthong, or from vowel to consonant or consonant to vowel in a syllable, or from one component to the other of a double or diphthongal consonant. Also, the vanish (or brief final element) or the brief initial element, in a class of diphthongal vowels, or the brief final or initial part of some consonants.
