one eyebrow salute
n.— «Some people do give what I call “the one eyebrow salute” when I tell them I’m a single male foster carer.…But I guess that’s down to the fact that it’s more common for guys to be seen as abusers rather than carers.» —“Why foster care can be rewarding man’s work” by Linda Summerhayes Scotsman (Glasgow, Scotland) Nov. 19, 2007.
