to boast
To speak about one's own achievements, possessions, or abilities in an exaggerated and self-satisfied way in order to impress others; to show off.
Er prahlte ständig mit seinem neuen, teuren Auto.
He constantly boasted about his new, expensive car.
When you want to say what someone is boasting about, use the preposition 'mit' followed by the dative. This structure is very typical for the verb.

'Prahlen' (to boast) has a strongly negative connotation. It describes not only that someone talks about their successes, but that they do so in an arrogant and unpleasant way.
Niemand mag ihn, weil er immer nur mit seinen Leistungen prahlt.
Nobody likes him because he only ever boasts about his achievements.
People often boast about things that are meant to show social status or success. Typical combinations are: 'mit seinem Geld prahlen' (to boast about one's money), 'mit seinen Kontakten prahlen' (to boast about one's contacts), or 'mit seinem Wissen prahlen' (to boast about one's knowledge).
Auf der Party prahlte er ununterbrochen mit seinen berühmten Kontakten.
At the party, he boasted nonstop about his famous contacts.
to please / to fall
'sich gefallen in' and 'prahlen' can both have to do with self-satisfied behavior. 'prahlen' means that someone talks openly and exaggeratedly about their own successes, money, or abilities. 'sich in etwas gefallen' is a more fixed and rather elevated expression: someone enjoys a role or behavior and clearly shows it. The person does not necessarily have to show off loudly. For ordinary showing off in everyday life, 'prahlen' is much more natural. 'sich gefallen in' fits better when describing an attitude or role.
Nach dem Spiel prahlte Tom mit seinen drei Toren.
After the game, Tom boasted about his three goals.
Er gefällt sich in der Rolle des klugen Beraters.
He revels in the role of the clever adviser.
