A verbal
mistake, when one accidentally and ironically fuses
two contradictory words together, which in this
case are 'exactly' and 'actually', thus creating a meaningless compound word. (Not to be confused with, 'It's actually', which sounds similar when spoken at a fast pace). Because of it's nature, when used, the word does not make clear whether or not the speaker means to continue or finish, since the word 'exactly' is usually a response which concludes an idea, and the word 'actually' signifies that there is more dialogue to come - therein
lies the humour.
Person 1: 'Hey we should go to Henry's Coffee House for
lunch.'
Person 2: 'No, it's way too expensive in there!'
Person
3: 'Exactually.'
Person 1: What? Did you
mean 'exactly', or did you
mean 'actually'? As in that you were going to suggest somewhere else instead?? You're not making any sense.
Person 3: Sorry! I meant 'exactly' but for some reason I had the word 'actually' in my head, and therefore said 'exactually' by accident! Sorry guys!
