MJBOLT:

the parrot should end up in a pot of soup before it puts somebody in trouble

NwaAmaikpe:




Her boyfriend is a gentleman with the fear of God.
If you gift me this type of wristwatch, God knows that the only time it will tell me is that it is time to break up with you.

Anyone who happily bought this trash for 5k obviously lacks a knack for taste and financial intelligence.
A lady who can't spot a fake from a mile away will not even know when she is ovulating.

These are the same ones that buy Baclenciaga, Gucsi, Varsace, Tom Fond, Tommy Hilfinger and Friendi for over 10k simply because they are in boutiques.

Tufiakwa biko, iberibe bu oria.

Nickshrapnel:
Bro, how many of such comments will you report? People here are too toxic, just leave them alone

TheExecutioner:
I'm willing to bet it was sarrki himself who posted that rubbish.

Only BMC clowns are so out of touch with reality.

Nowenuse:
Jos gets as low as 7°C at night, while at daytime it gets warmer because of the sunlight. But this warmth is only outside ooo, inside your house is still around like 11°C.
Pankshin should be around 4°C if Jos is at that temperature.

charles009:
Do you know what a proxy war is. Iran will be russias/northkorea/chinas proxys. If you think iran has enemies/america has thrice as much!

baganas:
He was fighting ISIS which is the creation of USA. ISIS are a terrorist group. terrorism according to the USA is politics by other means. How else can you infiltrate a sovereign state when you claim to promote democracy and all the falsehood associated with it. Terrorrise a state, create a humanitarian condition and then intervene and occupy, loot and kill to the content of your heart. This is the USA POLICY.

SangoOlukosoOba:
Kim would dare not.

That guy is another terror loading .

With China and Russia right behind him, that guy is close to an untouchable.

Stalwert:
An average bigoted Christian on nairaland lies 90% of the time. When Muslims conquered Spain they never tried forcing everyone to convert, the moment Christians recaptured the country, the began killing off Muslims till there were no Muslims in Spain. Muslim once ruled India yet till this date the Hindus are the majority, no Muslim army every set foot in Indonesia but today it is the largest Muslim country. Without lies, you bigots have nothing to offer, you accuse Muslims of crimes your fellow bigots wage against the rest of humanity.

@op better Iraq demands US leaves it is clear they have no regards for the people.

Sirjamo:
The Americans are in every single Muslim country either directly or indirectly. Wherever there are Muslims including Nigeria, they meddle in their affairs. If not for Russia and China, America would have nuked some Islamic countries since a very long time ago.

This is the type of injustice and forceful occupation of Muslim countries that breeded Al - Qaeda and ISIS !!!

sulasa07:
you think I care,bcoz it's USA,so it's not possible,right?
Too many Hollywood movies are making you think life is as movies,beta wake up

sulasa07:
looks like USA is afraid

itsme01:
how are you my old friend

SarakiBukola:
He was an APC supporter.

We, umu IPOB dey vex

sarrki:
Obaseki and his caucus won’t like this though
