- To grow some balls, as it pertains to the pursuit of women. The act of "suiting up" is a realization of values that make a man attractive to a woman, and a rejection of the values of a man that are idealized in women, but provide no success pragmatically in attraction. This includes rejecting notions of being nice, seeking to be liked for whom you are, and treating a woman well etc. Hence, "suiting up" is a moment of growth and acceptance of such things necessary to attraction as playing hard to get, being rich, being cocky, having good hygiene, and dressing well. This phrase is derived from the physical action of putting on a suit or "suiting up" in order to impress the ladies.

'Oh suit up
Tightly tied Bow tie
Shining cuffs put it all away
Don’t need them here
Oh dress up (softly)
The white veil that covers you
The soft lace, take it off
Don’t need to hide anymore
Suit-Up means: To lie on the matrimonial bed with the sexy beast, Kim Jonghyun on your wedding night. Undo his bow-tie and strip him slowly, and then consummate your marriage all night long.
