pop the question

Make this a summer to remember by popping the question.

She left town for two weeks and he popped the question on their next date.

But a lot can happen between popping the question and saying 'I do'.

She felt that any day he might pop the question, and her answer would be an immediate yes.

Sam knew that if he were to pop the question, she would say yes.

"I'm sure the both of them were waiting for you all these years to pop the question."

He popped the question, you said yes, so now it's time to party!

He had been seeing her for over a year now and yesterday she popped the big question.

This time, it was she who popped not the question, but the answer.

Neither can quite remember who popped the question, although each is pretty sure it was the other.
