Today I tried some acupuncture and I was lucky to get an appointment as the therapist said she had sessions back-to-back. This word is also heavily used in the business context – busy people have meetings back-to-back!
This means that things are happening one after the other, without a break.
Some more examples:
– The Knicks beat the Los Angeles Lakers, who won back-to-back championships in 2008-09 and 2009-10 (The Economist).
– Mr Leiken is a largely reliable guide to the varieties of Islamic belief and politics that are now reproduced in Europe, even if he can be a little clumsy with Arab and Asian names. He writes with eloquence, bringing to life the grim realities of the French banlieues and of the back-to-back houses of immigrant families in Leeds, where his requests for information met an impenetrable wall of silence (The Economist).
– It worries that it lacks the resources to fight two elections back-to-back, and will continue to push for an early poll (The Economist).
– For insurers as for Floridians, the recent pounding from four back-to-back hurricanes, costing $20 billion or so, has been highly unusual, as well as unwelcome (The Economist).
