1) To speak as though one has a cleft palate
Excited clefting - 'I really love those trousers {intermittent, incomprehensible hissing, like a Welshman saying Llanelli)'

Angered clefting- 'The cat has vomited in my handbag again {intermittent, incomprehensible hissing, like a Welshman saying Llanelli)'
