Barney is a womanizer who uses many 'plays' in his 'playbook' to help him have sex with women.
The character is known for his love of wearing expensive suits, laser tag, alcohol and various catchphrases, including "Suit up!", "Legendary", "Wait for it" (often combining the two as "legen—wait for it—dary!"), and "Daddy's home".
In later seasons, he has a few serious relationships, marries, divorces, and has a child with an unnamed woman from a one-night stand.
