General
butter
What does butter mean?
Mortar, in a bricklayer's mouth — and especially the act of applying it. You 'butter' a brick the way you butter toast: a smooth layer on the end before pressing it into place. Tells you the consistency they're after — spreadable, not soupy, not stiff.
"Butter the end of that brick and lay it tight to the line."
Origin
Trade slang from the obvious kitchen analogy — spreading mortar with a trowel mimics buttering bread.
