noun, Informal
1. any of various insects that sting or bite, especially a large American mosquito, Psorophora ciliata.
Never had seen nor heard this word used before and I doubt I'll ever use it...because I'd have to explain/define it to anyone hearing me say it and if I wrote it, I'd have to link to the definition on Dictionary.com
No, I think I'll just stick to my best and usual description, any one of various obscenities: slapping a mosquito on my arm and saying
"Take that, you little ^%#@*$!@ !!!"
