get under my boot

Something someone says to you to be extremely disrespectful, usually they're fake "alpha males" with a superiority complex and feel threatened by someone trying to do good in their own life. Used to put people down and feel better about oneself with extreme disrespect.

Ha! You're doing better in your life? Get under my boot.

Under the bus

Something to be kept secret; Kept in the closet

"Did you know those two are dating?"

"Yes, but they said to keep it under the bus."

Search under the bed

Searching under the bed means getting in the position to take it doggy style. On all 4s, arms and head down, ass up. Searching under the bed.

Nathan - Hey bitch, go search under the bed ;)
Patricia - But I want missionary!
Nathan - No, cunt, go search under the bed!
Patricia - Fine

Courage under fire

Bravery, while being judged, doubted, rejected, verbally abused, put down, surviving hard or difficult times. Coming through the fire, through the heat, and still being able to stand, to share your journey without shame or embarrassment.

Also, a movie, “Courage Under Fire”, staring Denzel Washington.

I’ve always admired Evelyn for showing courage under fire during her divorce from Matt.

Under the Milky Way

Sometimes when this place gets kind of empty
Sound of their breath fades with the light
I think about the loveless fascination
Under the Milky Way tonight

Lower the curtain down on Memphis
Lower the curtain down all right
I got no time for private consultation
Under the Milky Way tonight

Wish I knew what you were looking for
Might have known what you would find

And it's something quite peculiar
Something shimmering and white
Leads you here despite your destination
Under the Milky Way tonight

Wish I knew what you were looking for
Might have known what you would find
Wish I knew what you were looking for
Might have known what you would find

And it's something quite peculiar
Something shimmering and white
Leads you here despite your destination
Under the Milky Way tonight

Wish I knew what you were looking for
Might have known what you would find
Wish I knew what you were looking for
Might have known what you would find

Under the Milky Way tonight
Under the Milky Way tonight
Under the Milky Way tonight

The crusty film that forms made of sweat that collects under a breast, usually a large breasted girl, or woman.. or anyone who has breasts large or saggy enough to cause and form pockets, if its large enough to hide items, its large enough to collect dirt sweat lint and small creatures. Liken it to swamp ass or belly button lint..

Much to his surprise and horror when he got done licking there, there was some under flap stuck in his teeth
