Lady visits a guy at his hostel, crowd of guys wait outside to hail him

We understand the fact that Nigerians are the most hilarious set of Africans on Planet Earth. . and this again just proves it.
Apparently , a Lady visited a guy , in his hostel , mostly occupied by guys , and then after she came out, probably after a few servicing, other occupants of the room who waited for them at their door started “ hailing” and “ saluting” the Guy she came to visit ..
Perhaps hailing him for a job well done.
These people are mad..
