Dad: Son, what stands the term "RBF" for?

Son: Hi Dad,

"RBF" stands for "Replace By Fee". "RBF" allows to replace a stucked or unconfirmed transaction with a new one that uses a higher fee.

Dad: Son, this seems a useful feature to save fees.

Son: Yes.

Please note that the "replacement" transaction uses the same inputs as the original one.
