Tuck and Cover
When you (male) have a hard on (boner) and you need to go walk somewhere where there are other people that could see this so called boner, so you tuck your weiner up under the the top of your pants to cover it; therefore tuck and cover.
Female: shit what are you going to to with your boner? we have to go talk to my parents!
Male: its all good i'll just tuck and cover and they wont see a thing.
