Mosquito
A) someone very small, thin and annoying. Likes to be mean and stab backs. Thats why they are blood suckers.

b) a pesky insect that many people do not like. When you get bitten by one, (a female) your blood is being sucked. and when they are done you are left a little mark that itches like MAD. Males collect nectar.
