The speaker was talking about meeting new people when moving to university, and uttered this nice malaphor. It is a mashup of “clearing the air” (to remove doubt from a situation) and “breaking the ice” (to do something that reduces tension or unfamiliarity). I couldn’t help think that “breaking wind” (farting) might also have been in the mix, as wind and air might have been confused. However, farting was probably not what the speaker wants to do when meeting new people, and then again, perhaps a freudian slip? Anyway, it’s a nice mix up and a big thanks to bittenbyfrost for sending this one in!
