come undone
When something hits you out of left field and you can't help but cry. An unexpected solemn event that tends to swell up sad feelings.
Something about the way she said "goodbye" made me come undone.
come undone
coming so hard that you just go limp on the bed
every time we do it, she's so nice and tight that i come undone
Come undone
To come right before you girlfriend, preventing her from coming.
I come undone to her yesterday, and she was so mad at me!
