Baw-haired
To get somewhere in the nick of time or by a fine margin, a margin as fine as a single baw-hair.
"Just baw-haired another train tae Edinburgh. I was sweating like a beast by the time I got to my seat. If I'd have missed it I'd have had tae shell oot another £90 for the next fucking train. And it's a good job I didn't, cos I dinnae get paid til Tuesday."
